Hi we have a HP LJ 4345mfp printer, it is showing scanner initizing error. printer is working fine. Please hlep in this regard

This error can be caused by the following:

1. Fuser that is close to end of life. Maximum print quantity is 225,000 pages.

2. poor quality paper, very thin paper never feeds well and will jam.

3. Printing an image that is almost entirely black can cause the paper to buckle before entering the fuser.


Try different paper to see if that resolves the problem.

the problem may be the scanner are you able to scan to pc or email/fax from the machine glass/
when the machine initializes are there any faults displayed ( the printer will continue to function even if the scanner fails) usually the error code 30.01.02 or something like that will be displayed-
the scanner is connected via 1 large connector found to the rear of the machine - does the cable look damaged in any way- is the connection 'good' has the grounding wire worked loose, if after these have been checked there is still no scanner then you may need either a scanner or main PCA/formatter fot the printer.
Belmonte business are able to help with the repair of this unit should it be required and would be subject to the usual costs.

To initialize NVRAM, turn the printer power off. Remove any installed accessories (for example, a stapler/stacker). Turn the printer power on, and then hold down (SELECT button) when the memory count begins. Continue holding down until all three printer control-panel lights flash once and then remain on. This might take up to 10 seconds. Press (UP ARROW button). Press the PAUSE/RESUME button (LJ 4200/4300) or the MENU button (LJ 4250/4350). The display should show SKIP DISK LOAD. Press (UP ARROW button) until NVRAM INIT is highlighted. Press (SELECT button) the printer initializes NVRAM and then continues its power-on sequence.

Better to replace the farmatter assm, chances are too low to recover the formatter.

Hi

my friend your memory card is not working
you need to replace memory on printer

HP Laserjet 4345MFP
Backlight on printer display does not light.
Counts up the 256MB memory then HP logo (3 sizes) appears (just visible)
The 3 lights keep cycling on the display. Thats it, does nothing else.
It has been left overnight and continues to display the logo and cycling 3 lights.
Rear DC Cont Fan is turning. No other fans or activity with machine.
When ADF/scanner/mfp or hard disk are disconnected it does recognise this and throws an error and asks for reboot.
I have tried cold reset, nvram init. and hard disk init. but no difference.
Your thoughts?

the scan borad on is back change it
