Did you try to call their customer support? I had a problem with mine a couple of weeks back and they immediately sent someone to fix the problem.

Repair guy said printer head was stuck in a non-engaged position and needed changing. costs of parts + times meant it was better to buy a new laserjet canon. Much better than the solid blocks and no need to buy maintenance kit!

Throughout print job HP laserjet 9050 print will be squigly/flakey and not fuse to paper properly

when you replaced the maintenance kit - did you replace the Fuser assembly as well - as this faultr is down to the pressure off the fuser roller to fix the image also there are two blue tabs that set the fuser unit to letter mode(less Pressure) these can be accessed without removing the fuser and are accessible from the left door. ensure the levers are set to paper and not letter. if the fuser is still not fixing the image correctly then a new fuser unit assembly is required as fuser units are non servicable.

Lexmark T642 print gray though new cartridge


The main cause of light print is a bad set of charge and transfer rollers. These rollers are used to put a charge on the paper and transfer the toner to the charged paper. When the rollers get worn out they can not put the proper electrical charge on the paper so the toner does not stick to it as it should. One roller sits under the toner cartridge and on is on top on the cartridge. If you pull out the toner and look inside the printer you will see the transfer roller and if you start to close the lid with the toner out you will see the charge roller come into view. Here are pictures of each one. Transfer roller first.



These rollers come in the preventative maintenance roller kit. This kit is available at the following link. The kit also comes with the pickup rollers.

What do I do with the screen saying Maintenance?

Maintenance message means that you will need to order a maintenance kit for that printer. In a maintenance kit usually comes a new fuser core, transfer roller, and feed tires.

The fuser core is used to heat up the ink and permanently affix it to the paper before it comes out on the top tray.

If the printer still prints fine, and depending on how much printing you actually do on this, you may be able to get away with not needing to replace the maintenance kit for a couple more weeks.

I have a xerox 8400 printer and the ink is sticking to the drum. I have installed a new maitinance kit but am still having the problem. Please help

There are three possible solutions.
Try running the 'remove print smears' routine from the print quality troubleshooting menu. You may have to run it 5 or 6 times to completely clean the drum.
It may be that the drum maintenance pivot plate is cracked, this causes the plate to press the maintenance kit on to the drum unevenly. You will hear a ripping sound as the paper exits the printer, this is due to it literally ripping the ink off the drum. Being an 8400, if your pivot plate (the assembly that your maintenance kit slides on/in to) is white (off white) in colour, my money is on that being cracked.
The third possibility is that the cam shaft that pushes the pivot plate up to the drum has loose/spinning cams which again, will cause the plate to press unevenly.
Hope this helps.

No matter what tray I print out of my dell 5200 laser, I get a paper jam. Any ideas?

The roller inside of your printer are responsible for guiding the paper through your printer properly. As time passes, these rollers become worn and subsequently don't feed paper through your printer correctly any longer.

To resolve the problem, you can purchase a maintenance kit for your specific printer which will contain new rollers and other parts that are known to require periodic replacement.

This link will give you an example of the maintenance kits available for your printer.

Before you decide to purchase a maintenance kit, it would be a goood idea to do some price checking as the price can vary widely. Typically, a maintenance kit purchased from the manufacturer will cost substantially more than a "compatible" maintenance kit made by some other manufacturer.

Fuser roll has big dents in it, says unable to print

Dear Computer_tea,

If the fuser is damaged as you say, you will need to replace it. The unit will not print correctly and the image quality will be very poor.
The fuser unit is part of the maintenance kit, and unless you replace the maintenance kit, it will still say the same. You will need to replace the kit and now for the bad news.

The maintenance kit is going to cost you over $500.

You will need to consider very carefully befor you go out to buy a kit as these printers can be purchased for around $900 new.

Print Quality - Shadowing

What does the white roll on the maintenance kit look like?
Is it really dirty? It could be either the kit, maybe the ink.
But in partiular if the kit was stood on end and not stored laying flat, the lubricant in the kit may have saturated one side and depleted on the other.
I have never seen the non Xerox ink, and have no clue if it would cause a problem like that.
I suspect a maintenance kit, that it is dry on one end.

Does it jam at the fuser when doing a single print?

These machines have a Maintenance kit required every 200 000 prints, these MK's include all feed rollers, a transfer roller and the entire fuser assy. To replace the kit fixes all issues I've seen in these printers besides when the cartridge affects print quality.

If it is jamming at the fuser on a single print done via the printer operations panel, and your paper is fresh, it could only be the feed roller having trouble gripping the paper or the fuser not turning/stuffed.

Feed Kit, I have my doubts as to this being your problem

Maintenance Kit Fixes 98% of the time

Was is noisy before it died?
I have seen a few with stuffed fuser drive gears but not many and customers could hear it wearing.

How many prints since last MK? via keypad print a configuration page, count is there ie pages since last maintenance xxxxxx
