I have Printer Laser jet HP P2055d error code is 59.f0 i need some one help thank you

Okay let's try this please.

Below is a recommended suggestion to resolve this problem:
  1. Upgrade the FW
  2. Remove the ITB
  3. Remove the fuser and on the left side (front of printer side) you can see the sensor flag holder (image #1 and #2 below)
  4. If the sensor flag/lever is stuck in the up position then reach in and carefully release the part with your fingers. The images below show the sensor flag/lever stuck in the up position. Actuate the flag/lever a few times to make sure it is loosened up.
  5. Re-install the ITB
  6. Re-install the fuser
  7. Reboot to see if the error clears
If the issue returns in a short period of time, then the flag/lever is likely dragging and returning slowly or getting stuck again. If this occurs, then it is recommended to:
  1. Remove the top cover
  2. Inspect the POSITION DETECT ASSY RM1-5604 to ensure the photo interupter is seated correctly
  3. Check the sensor flag for proper movement
  4. Replace the POSITION DETECT ASSY RM1-5604
NOTE: The ITB is typically not the cause of this issue.
I hope this helps.

I have a Canon Image Class 8580 CDW with Error E070-0000 Changed the Fuser could it be the Transfer ?

The code due to, ITB/TOP sensor defect, DC controller PCB defect.
Do the procedure to check yourself.
1. Turn off the printer.
2. Hold down the Resume / Cancel Press the POWER - indicator turns green.
3. Release the Resume / Cancel, still holding the POWER.
4. Press the Resume / Cancel 2 times while holding POWER, then release all buttons.
5. When the indicator light remains green - press the Resume / Cancel 4 times.
6. Turn off the printer button POWER. Then turn, this should solve the problem.

If the problem not clear, take the help of trained service engineer to check the connector of the ITB unit, DC controller PCB. • Replace ITB unit • Replace DC controller PCB.

Hello, I replaced the fuser on my 734de and I still get fuser life warning

Did you replace the fuser with a new Lexmark fuser or a refurbished unit? The original Lexmark units have a chip in them that resets the counter when installed. However this only works the first time the fuser is installed. If you install a used fuser in a different printer it will not reset the counter.

How do i reset fuser count on lexmark c792de

lexmark 792 printer are reset based on a chip in the fuser. The fuser must be replaced. Make sure you completely power off the printer before you remove and replace the fuser.

When I turn my printer on, the red light stays on and I can't print

Are any of the toner lights lit? Then the problem is you are out of that color toner and must replace it.

If the toner lights are off, then the printer has an error that must be corrected. Check for a paper jam, an open cover, no paper in the tray (or not being picked up by the rollers), the waste toner container being missing or full.

The other errors that could be at fault are service errors: LSU (laser unit) error, fuser error, or ITB
error. For these, you need to contact Samsung support for the part numbers. The fuser should last 100,000 pages. The ITB has an expected life of 60,000 black and white pages and 15,000 color pages. Samsung recommends these be replaced by a certified technician.

The unit will not print until the fault is fixed.

I hope this helps.

Optra T612 fuser replacement

Here's an article in the Lexmark website on How to Replace the Maintenance Kit Parts on an Optra T Laser Printer. Just click on this link: Scroll down for the instructions on how to replace the fuser unit. Hope this helps.

I have a lexmark T630 and the fuser needed replacement, now the printer will print just fine with one problem. On every page that prints out there is about 2in from the left side of the paper light print....

Light print is usually caused by a bad charge roll or transfer roll. Can also be caused by a bad HVPS, which I hope is not. But try cleaning the charge roll. Check the transfer roll, it may have shifted all the way to the left. Hope this helps. If you need more assistance, leave a comment and I'll get back to it. Thanks.

Fuser life on screen please advise

When Fuser Life message on the screen of your Lexmark X502n printer is displayed, replace the fuser immediately, For your reference, check this article in the Lexmark website. Just click on this link: . There are also links on that page on replacing the fuser and resetting the fuser page count. Hope this helps.
