Re: 925.01 service fuser error

Hi The Fuser has failed meaning the temp of the fuser is to high or to low. In order to fix this error you can try powering down the printer for 10 to 15min and retry . I think though you will have to call for service or replace the fuser yourself!!! I hope I have helped.

Hp t1100 error 50.2

  1. Remove the printer from any UPS supplies, additional power supplies, or power strips.
  2. Plug the printer into a wall outlet to check whether this resolves the problem.
  3. If the printer is already plugged in, try another power source in the building independent of the one being used.
  4. The line voltage and current source at the printer location might need to be inspected to make sure that it meets the printer's electrical specifications.
  5. Turn the printer off then on.WARNING: Be careful when removing or reseating the fuser. Temperatures can reach 400+ degrees Fahrenheit.
  6. If the message persists, turn the printer off for 30 minutes to allow it to cool, then reseat the fuser after checking the internal wiring connections on the right and left side, ensuring that these connections are properly seated.
  7. If the 50.1 or 50.2 error recurs after power-cycling the printer or when trying to print, try installing a known good fuser from another HP LaserJet 4100 series printer, if available.
  8. If the fuser is near or at the end of its estimated life expectancy (approximately 200,000 pages), then replace the fuser. After replacing the fuser, print a Configuration page, a Menu map (shows fuser settings), an Event log, a Supplies status page, and a Usage page, to reference the status of the new fuser and to ensure that the previous fuser settings are in place with the replacement fuser. To print an Information page on the HP LaserJet 4100, perform the following steps
    1. Press the MENU rocker key until INFORMATION MENU appears on the printer display.
    2. Press the ITEM rocker key until PRINT CONFIGURATION (or until PRINT MENU MAP, etc, appears in the printer display.
    3. Press the SELECT button to print the selected information page.
    To print an information page on the HP LaserJet 4100MFP, perform the following steps
    1. Press the MENU button.
    2. Press the DOWN Navigation button until INFORMATION is highlighted.
    3. Press the RIGHT Navigation button.
    4. Press the DOWN Navigation button to highlight PRINT CONFIGURATION (or PRINT MENU MAP, etc, appears in the printer display.
    5. Press the SELECT button, the button with the checkmark on it to print the selected Information page.
  9. If 50.x errors persist after properly installing a known good fuser, or if the errors follow the questionable fuser (provided it is not near the end of its estimated life expectancy), contact HP for further assistance.

HP laserjet 3600 error message 50.9 Fuser Error

Thank you for the inquiry.
Yes you will probably have to replace the fuser. If this is a new printer still under warranty and the page count has not reached the service life of the fuser, contact HP for warranty replacement. Once the new fuser in installed you will need to restore the service count.
Fuser Kit Part Number: (Sometimes Called a Maintenance Kit)
RM1-2665 This fuser is compatible with the following printers: HP Color LaserJet 2700, 3000, 3000N, 3000DN, 3000DTN, 3600, 3600N, 3600DN,
Link to Installation pictures and instructions:
Restoring the maintenance count after installing new fuser.

This printer tracks the number of pages printed on the fuser, and a reminder message will appear when the fuser reaches a certain page count. The message will instruct you to replace your fuser. Whenever you install a new fuser, you should reset the fuser page count so the warning message will not appear prematurely.

To reset the fuser count :
1. Press MENU to enter the MENUS.
2. Press Down arrow to highlight Configure Device.
3. Press Checkmark to select Configure Device.
4. Press Down arrow to highlight RESETS.
5. Press Checkmark to select RESETS.
6. Press Down arrow to highlight RESET SUPPLIES.
7. Press Checkmark to select RESET SUPPLIES.
8. Press Down arrow to highlight NEW FUSER KIT.
9. Press Down arrow to select NEW FUSER KIT.
10. Press Down arrow to highlight YES.
11. Press Checkmark to select YES.

The fuser count will be reset and then the printer is ready to use.

Lexmark C772n - 127.07 Service fuser error

I searched the Technical Manual and there is no explanation of the code. The user manual simply says there is a printer failure. They ask that you turn the printer off, wait 10 secs and then restart. Then call 1-800-LEXMARK and they will tell you about the code.

Given that your printer is saying Service Fuser, it is highly likely the fuser is ready for replacement. The fuser is the component that heats to high temperature to fuse the toner to the paper and complete the print cycle.

Hp 4550 vertical line down center of page

From the service manual:

Vertical lines or streaks
 Check for a leak where light might be entering the printer.
 Check for circumferential scars on the photosensitive drum. If scars are present, replace the
drum cartridge if the line goes through all colors.
 Check for circumferential scars on the upper fusing roller. If scars are present, replace the upper
fusing roller if the line goes through all colors.
 Remove the imaging drum and inspect main charger or imaging drum for a contaminant, such as
a fiber, if the line goes through all colors.
CAUTION Do not expose the imaging drum to light for more than 15 seconds. The drum is light sensitive, and
exposure to light can cause permanent damage.
Vertical black lines
 The toner cartridge is defective.
 The toner cartridge is not seated properly.
 The fuser entrance is dirty.
 The fuser has scratches on it.
 This might be a repetitive defect. If so, the lines will repeat at a consistent interval down the page.
 The printer needs to be cleaned.
 There is a problem in the heating element.
Vertical white lines
 If white lines or streaks appear only in the black areas of the printed media, print several
configuration pages to clear the anomaly. If this does not clear the problem, check the sleeve
surface to confirm the defect, then replace the black toner cartridge.
 If white lines appear only in a particular color, try printing several configuration pages to clear the
error. If the error does not clear, check the sleeve surface to confirm the defect, then replace the
defective toner cartridge.
 There is a lack of toner or the toner cartridge is faulty.
 There is dirt in the laser path.
 The fuser is defective.
 A mirror in the laser scanner is dirty.

Line across the page

  1. Make a copy by using the platen mode and ADF.
  2. Send a print from your PC or print out the Counter list from User tools/counter button.
  3. Try printing one colour at a time - Black, Cyan, Yellow or Magenta.
If when printing, there is no line across the pages, so you need to clean the optics mirrors and exposure glass.
If the line appears in both 1 and 2 mentioned above, you have the fuser roller or drum damaged.
If the line appears in all colour prints, check the fuser or transfer belt.
If it happens only with one particular colour, check that drum unit.

Good luck and please rate me, thanks.

Double page copies and CRU Error

CRU Fuse error equates to a problem the machine has reading the print cartridge installed in the machine. It has nothing to do with the fuser.
Suggest that you change the print cartridge.
