HP 2840 printing two thin black lines from top to the bottom of the center of the page is that a fuser kit problem?


It could be a fuser problem.
Put paper in the manual feed tray. Print a few pages. As the paper gets
1/2 way into the printer, open the cover. Look down at the paper in the printer.
If it has 2 thin black lines, the toner cartridge needs to be replaced. If there are no lines the fuser is probably bad.

Any size paper we send through the printer comes out with a fine black line on the left side. Printer is p3005x


It is either the fuser or toner cartridge. Try a known good toner cartridge. If this solves the problem, then you have a bad toner cartridge. This can often occur when cartridge is near "end of life".
If this doesn't solve the problem, then most likely it is the fusing assembly. You can also try a "half page" test print. Stop the printing in the middle by opening the toner cartridge access door before the paper reaches the fusing assembly. "No defects" , then I would strongly suspect the fusing assembly. HP is replacing these fusers based on Mfg date. of the printer. Call HP if it is a fusing assembly problem.

Each time the printer goes to print the paper


Either you have a problem with the fuser itself, such as a drive gear problem where the fuser is not turning or the is toner buildup on the fuser entrance plate. The toner buildup is a common problem so I would check that first. The fuser is easy to remove and you just beed to flip it over and look closely at the plates that "guide" the paper into the fuser rollers. Look for any small globs of melted toner that the paper is hitting when it tries to enter the fuser. If you let it cool down first then the toner can usually be chipped away and scraped clean. Then just reinstall.
Good Luck.

Hp laser jet 2430 dtn prints lines on left side of paper


Hi Karent503:
It sounds like you fuser assembly is worn. The part on the fuser assembly that you are having a problem with is the heat roller assembly located in the fuser. You can have a technician replace that for you at you local HP repair center, Her is the part number for the fuser assembly.

Fuser, 110-127 V RM1-1401-000CN

Ghost prints on HP-1300


The cartridge could be bad. Just saw same issue earlier on another HP doing the same. Inspected the fuser and it had a place it the middle that the teflon coating was worn off. Try cartridge first, then look at the fuser with flashlight. Do not stick anything into the fuser. Make sure machine is powered down,unplugged and allow it to cool down before attempting to touch area. It will burn you, they get hot!

Hp 2420 vrtical line in page


Hello,

This issue can be due to fuser. I am sure you have changed the toner cartridge.
To confirm its a fuser issue, please perform the following:
1. Try printing a configuration page from tray 1, pull the top cover, as soon as the media is 60-70% inside the printer.
This would stop the paper before reaching the fusing assy.
2. Remove the paper and check if the line exist.
If exists, fuser is not faulty.
If it does not, then transfer roller, laser/scanner assy is faulty

- If fuser is faulty, perform the cleaning page as following
1. go to configure device > print quality > create/process cleaning page
perform cleaning page 5-6 times, however, if the line is due to fuser, then fuser needs to be changed.

Let me know the next update.

Change the toner cartridge, refilling will not solve the problem.

Dirty copies


When you replaced the drum did you printed like 15 pages? Did you noticed any change in the ouput of the line did it fade?, if you are 100% sure that the cartridge is ok., then check the fuser and/or the transfer roller. Make sure that the printer is clean inside.
