Re: Test Page blachy, text faint, supplies staus page bar...

Have you tried the toner cartridge?? IF not please do so. Failing this clean out the middle of the machine with a dry cloth as you may have loose toner in there. Try this if it doesn't work then the laser unit may have a fault.

Hope the first one helps
Thanks J

Hp lj 2430 rumbling noise

This is caused by the wearing of gears that drive the fuser assembly situated at the rear of the printer. Also the pressure roller bushes in the fuser assembly are worn.

Hi, I just aquired an HP 4600n color laser printer, it is used but it works good for text but when printing pictures it prints a really bad quality mainly due to a buch of (mostly yellow)lines running the...

First. Examine the toner cartridges by inspecting the surface of the drum of each color cartridge. Score marks? Replace toner cartridge(s).
Next. for vertical lines from top to bottom, you will want to inspect the fuser real quick to see if the Hot roller is scored or worn or discolored or any adhesives are adhered to roller. Should be perfectly smooth and uniform in color.
Next, do the consumables life page which is in a menu function.
Information --> Supplies Status Page.
This will tell you the life remaining of the image transfer kit (C9724A) as well as fuser unit. These indicators will help you decide if the consumables are the first cause of the print quality issues you are observing.

Vertical lines of missing print

I'd certainly be swapping the fuser first although I know how expensive they can be and what a pain they can be to get at. You've tried everything else I would start with and as the text is smudging I'd certainly be testing the fuser next. Scott.

HP4345 MFP printer and the print quality is fuzzy. I put in a new toner cartridge and that didn't work and i also created a cleaning page and that didn't help. what next? just had the tech out here last...

Fuzzy print is mostly related to 3 items in your printer. 1 the toner cart. 2 fuser. 3 transfer roller. A fuser replacement is a normal fix for this problem. Check your PM kit status by printing a supplies status page. A PM kit will have a fuser, transfer roller and feed rollers. If the PM level is low ,order and replace kit. If not you may want to get a new fuser

Printing Problem

Image defects on LJ printers are usually the toner cart. or the fuser:

This is the test to determine toner or fuser issue.
Print a test page
When you hear the paper feed into the machine open the top to stop the machine
Remove the toner cart.
You should be able to see the page with printing on it. (This is before the page hits the fuser)
If you can see the image Defect on the page the problem is most likely the cartridge but NOT the fuser.
If the page is clean the problem is most likely the fuser.
Hope this helps

I have black vertical lines


Black vertical lines could either be a scratch on the drum or a dirty charging corona wire. Order a new drum and clean the Corona with a brush. Image of Corona This should resolve the issue.

HP Color LaserJet 2600n Printing Problem!


It sounds like you are having an issue with your fusing assembly. Here's the check you need. Measure the distance from the original print on the page and the exact spot where the repeat ghosting (same spot) appears on the page again. Here's the distances that identify the part having an issue. My guess and experience with this printer says it's probably fuser. Seen a lot of 2600n printers with image ghost problems and almost all are fuser related.

2.22" or 56.6mm = Fuser Upper Film
2.47" or 62.8mm = Fuser Lower Roller (Usually Backside)

2.97" or 75.4mm = Toner Cartridge - Drum (Usually One Color)
0.97" or 24.7mm = Toner Cartridge - Developer Roller
1.05" or 26.7mm = Toner Cartridge - Primary Charge Roller

2.15" or 54.5mm = ETB - Transfer Belt (Big Belt on Door)

If it should be the Fuser or Transfer Belt, consider not replacing the part as the minimum cost for either (part only) is $105.00 before shipping. The better alternative is to jump on Ebay and buy a HP refurb or new machine MINUS the supplies. They come with the Transfer belt and fuser. They are cheaper for the full machine than the replacement part. They average about $65.00 thru $90.00 landed.

Hope that helps you. If so, hit me with a FIXYA.

LJ 2430 Printing Blank Pages

HI there have you tried the toner cartridge as this could also cause this problem? Also change the transfer roller and are the bands going from left to right or from up to down. If the bands are left to right change both if up to down more likely to be the toner cartridge.

Hope this helps you
Thanks J

Consistent, faded and streaking vertical lines across entire page, from top to bottom.

Toner issue getting to drum - use gen toner cart.

or Drum blade stuffed (lines are down page fro top to bottom- replace drum assy

Drum has been exposed to light faint or blank across copies repeated 4 times down page - replace drum assy

or upper fuser roller stuffed, down page, smudgy print -  replace fuser

LSU(laser) or boards rarely cause issues
