Fuser protection function
When the protective function detects an abnormal temperature rise in the fuser, it interrupts the power supply to the fuser heater. The following components prevent an abnormal temperature rise of the fuser heater:
●
DC controller: The DC controller monitors the detected temperature of the thermistor. The DC controller makes the fuser heater control signal inactive and releases the relay to interrupt power supply to the fuser heater when it detects that the thermistor temperature is 240° C (464° F) or higher.
●
Fuser heater safety circuit: The fuser heater safety circuit monitors the detected temperature of the thermistor. The fuser heater safety circuit releases the relay control circuit to interrupt power supply to the fuser heater when it detects that the thermistor temperature is 265° C (509° F) or higher.
●
Thermoswitch: The contact of the thermoswitch is broken to interrupt power supply to the fuser heater when it detects that the temperature fuse is 230° C (446° F) or higher
Fuser failure detection
The DC controller determines a fuser failure, makes the fuser heater control signal inactive, releases the relay to interrupt power supply to the fuser heater, and notifies the formatter of a failure state when it encounters the following conditions.
●
Start-up failure
◦
If the detected temperature of the thermistor is kept at a specified temperature or higher for a specified period of heater start-up during the wait period.
◦
If the detected temperature of the thermistor is kept at a specified temperature or lower for a specified period under the heater temperature control during the initial rotation period.
◦
If the detected temperature of the thermistor is kept at a specified temperature or lower for a specified period under the heater temperature control during the print period.
◦
If the detected temperature of the thermistor does not reach its targeted temperature within a specified period under the heater temperature control during the initial rotation period.
●
Abnormal low temperature
◦
If the detected temperature of the thermistor is kept at a specified temperature or lower for a specified period under the heater temperature control.
Chapter 1 Theory of operation ENWW
●
Abnormal high temperature
◦
If the detected temperature of the main thermistor is kept at a specified temperature or higher for a specified period.
●
Drive circuit failure
◦
If a specified frequency of the frequency signal is not detected within a specified period after the product is turned on.
◦
If an out of specified frequency of the frequency signal is detected after the product is turned on.

Protective function
The low-voltage power supply has a protective function against overcurrent and overvoltage conditions to prevent failures in the power supply circuit. If an overcurrent or overvoltage event occurs, the system automatically cuts off the output voltage.
If the DC power is not being supplied from the low-voltage power supply, the protective function might have activated. In this case, turn off the power switch, and then unplug the power cord. Do not plug in the power cord or turn the power switch on again until the root cause is found.
16 Chapter 1 Theory of operation ENWW
In addition, two fuses in the low-voltage power supply protect against an overcurrent event. If an overcurrent event occurs in the AC line, the fuse blows and cuts off the power distribution.
Safety
For safety purposes, the product has a function to interrupt the 24V power supply to the fuser and the high-voltage power supply. The door switch is turned off and 24V power stops if the cartridge door is opened (SW301 is turned off).
The product has the power switch on the DC line, so if the AC power flows, even the power switch is turned off. Be sure to unplug the power cord before disassembling the product.
Low-voltage power supply unit failure detection
The DC controller determines a low-voltage power supply failure, stops 24V output and notifies the formatter when it detects that the 24V output is higher than the specified voltage.
ENWW Engine control system 17
Laser scanner system
The laser scanner system forms a latent image on the photosensitive drum according to the video signals sent from the formatter.
The main components of the laser scanner are the laser assembly and the scanner motor assembly, which are controlled by the signals sent from the DC controller.

Image-formation process
Laser printing requires the interaction of several different technologies including electronics, optics, and electrographics to provide a printed page. Each process functions independently and must be coordinated with the other processes. Image formation consists of the following processes:
●
Latent-image formation
●
Development
●
Transfer
●
Fuser
●
Drum cleaning
These processes are divided into seven steps, which are shown below and described in the following sections.

Latent-image formation stage
During the steps that comprise this stage, a latent image is formed by applying a negative charge to the photosensitive drum. You cannot see this image on the drum.
ENWW Image-formation system 21
Step 1: Primary charging
To prepare for latent image formation, the surface of the photosensitive drum is charged with a uniform negative charge. The primary charging roller receives the primary charging bias, and then the roller charges the drum directly.
Figure 1-15
Primary charging process
Primary charging roller
Primary charging bias
Photosensitive drum
Step 2: Laser-beam exposure
The laser beam scans the photosensitive drum to neutralize the negative charge on portions of the drum surface. An electrostatic latent image forms where the negative charge was neutralized.
Figure 1-16
Laser-beam exposure
Laser beam
Unexposed area Exposed area
Developing stage
The developing roller contacts the photosensitive drum and deposits toner on the electrostatic latent image, which becomes visible.
Step 3: Development
Toner acquires a negative charge as a result of the friction from the developing roller rotating against the developing blade. When the negatively charged toner comes in contact with the drum, it adheres to
22 Chapter 1 Theory of operation ENWW
the electrostatic latent image. When the toner is on the drum, the image becomes visible. The developing bias is applied to the developing roller.

ENWW Image-formation system 23
Transfer stage
During the transfer stage, the photosensitive drum transfers a toner image to the paper.
Step 4: Transfer
The transfer bias is applied to the transfer roller to give the paper a positive charge. The positively charged paper attracts the negatively charged toner from the photosensitive drum surface.
Figure 1-18
Transfer process
Photosensitive drum
Paper
Transfer roller
Transfer bias
Step 5: Separation
The elasticity of the paper and the curvature of the photosensitive drum cause the paper to separate from the drum surface. The static charge eliminator reduces back side static discharge of the paper for stable paper feeding and image quality.

24 Chapter 1 Theory of operation ENWW
Fusing stage
Until the fusing stage is complete, the image is not permanently affixed to the print media. The toner can be easily smudged until the heat and pressure of the fusing process fix the image to the sheet.
Step 6: Fusing
The product uses an on-demand fusing method to fuse the toner image onto the media. The toner image is permanently affixed to the print media by the heat and pressure. The fusing bias is applied to the pressure roller to improve image quality.

ENWW Image-formation system 25
Drum cleaning stage
Not all of the toner is removed from the photosensitive drum during the transfer stage. During the cleaning stage, the residual, or waste, toner is cleared from the drum surface to prepare the surface for the next latent-image formation.
Step 7: Drum cleaning
The cleaning blade scrapes the residual toner off the surface of the photosensitive drum and deposits it in the toner collection box. The drum is now clear and ready for the next image-formation process.

Repetitive image defect ruler
Defects on product rollers can cause image defects to appear at regular intervals on the page, corresponding to the circumference of the roller that is causing the defect. Measure the distance between defects that recur on a page. Use the following table or the repetitive-defect ruler to determine which roller is causing the defect. To resolve the problem, try cleaning the roller first. If the roller remains dirty after cleaning or if it is damaged, replace the part that is indicated in the following table.
CAUTION:
Do not use solvents or oils to clean rollers. Instead, rub the roller with lint-free paper. If dirt is difficult to remove, rub the roller with lint-free paper that has been dampened with water.
NOTE:
The following table replaces the graphical repetitive defect ruler. You can make your own ruler by using these measurements. For the most accurate results, use a metric ruler.

Check the document that you are printing to see if content appears on all of the pages.
To check the product, print a
Configuration page.
Print on a different type of media.
Pages print very slowly.
NOTE:
The product print speed is effected by various factors (for example, media size or page complexity).
Pages did not print.
Heavier media types can slow the print job.
Complex pages can print slowly.
Paper type not set correctly.
The product might not be pulling media correctly.
The media is jamming in the product.
The USB cable might be defective or incorrectly connected.
Other devices are running on your computer.
Proper fusing might require a slower print speed to ensure the best print quality.
Select the type to match the paper.
Ensure paper is loaded in the tray correctly.
If the problem persists, you might need to replace the pickup rollers and the separation pad.
Clear the jam.
●
Disconnect the USB cable at both ends and reconnect it.
●
Try printing a job that has printed in the past.
●
Try using a different USB cable.
The product might not share a USB port.
If you have an external hard drive or network switchbox that is connected to the same port as the product, the other device might be interfering. To connect and use the product, you must disconnect the other device or you must use two USB ports on the computer.
96 Chapter 2 Solve problems ENWW
Print speeds
Print speed is the number of pages that print in one minute. Print speed depends on different engineprocess speeds or operational pauses between printed pages during normal product operation. Factors that determine the print speed of the product include the following:
●
Page formatting time
The product must pause for each page to be formatted before it prints. Complex pages take more time to format, resulting in reduced print speed. However, most jobs print at full engine speed
(35 ppm on Letter-size media or 33 ppm on A4-size media).
●
Media size
Legal-size media reduces print speed because it is longer than the standard Letter- or A4–size media. A reduce print speed is used when printing on narrow media to prevent the edges of the fuser from overheating.
●
Media mode
Some media types require a reduced print speed to achieve maximum print quality on that media.
For example, glossy, heavy, and specialty media (for example, envelopes or photos) require a reduced print speed. To maximize the print speed for special media types, ensure that you select the correct media type in the print driver.
●
Product temperature
To prevent product damage, print speed is reduced if the product reaches a specific internal temperature (thermal slow down). The starting temperature of the product, ambient environment temperature, and the print job size effect the number of pages that can be printed before the product reduces the print speed. Thermal slow down reduces print speed by printing four pages and then pausing for an amount of time before printing continues.
●
Other print speed reduction factors
Other factors (especially during large print jobs) that can cause reduced print speeds include:
◦
Density control sequence; occurs every 150 pages and takes about 120 seconds.
The product does not print or it prints slowly
The product does not print
If the product does not print at all, try the following solutions.
1.
Make sure the product is turned on and that the control panel indicates it is ready.
◦
If the control panel does not indicate the product is ready, turn the product off and then on again.
◦
If the control panel indicates the product is ready, try sending the job again.
2.
If the control panel indicates the product has an error, resolve the error and then try sending the job again.

Toner consumption
EconoMode uses less toner, which might extend the life of the toner cartridge. HP does not recommend the full-time use of EconoMode. If EconoMode is used full-time, the toner supply might outlast the mechanical parts in the toner cartridge. If print quality begins to degrade and is no longer acceptable, consider replacing the toner cartridge.
Paper use
This product’s manual/automatic duplex feature (two-sided printing) and N-up printing (multiple pages printed on one page) capability can reduce paper usage and the resulting demands on natural resources.
