Hp lasject 4050a toner cartridge have black line in the paper


The vertical lines can be caused by a damaged fuser assembly. The fuser heats the toner and melts it onto the paper. The roller is covered with teflon and when it gets worn down it leaves streaks or "ghost" images on the paper. Here is an article dealing with the lines on a Laserjet 2100 printer but the cause is the same for the 400 and 4050 series printers. Check your fuser as per the information in the above article and if need be order a replacement fuser from somewhere like Amazon.

Black line on right hand side of the pahe

This usually indicates the the Teflon coating on the fuser roller is damaged and will need to be replaced. The fuser is the part at the back of the printer that heats the toner and fuses it to the paper. The heat roller is coated with Teflon so the toner does not stick. If something scratches this coating the toner will stick and come off on the paper in a line where ever it is damaged. Here is a link to an article showing how to check the toner, the guide is for the 2100 printer but the issue is the same.

Hp 2420 leaves vertical line across the page. we changed the fuser 7 months ago


It sounds like you may need to change it again. These printers use a Teflon coated heat roller in the fuser. If you print envelopes that will scar the heat rolller, this can also happen if there is a piece of paper jammed in the fuser assembly and it scraped the fuser roller. Open the back of the printer and look at the roller in the fuser. I would bet that you see the roller is damaged. Here is a link to a post about the Laserjet 2100 printer with the same issue. It has pictures of the roller and what to look for, the fuser is different but the principle is the same.

I hope this helps, if so please rate my solution.

How to solve Paper jam and Printer Jam Issues of Laserjet 2100?

Hello muhmmadk890,
Assuming that your printer has had a lot of mileage, it may be time for a maintenance kit. the following link is an example, before making any purchase be sure that it is for the exact model.
Aside from replacing rollers, you can attempt to clean rollers that appear to have grime. There are plenty of products available for cleaning rollers, but in my experience just looking at them for wear, and cleaning with a paper towel, and or fingernail has done the job well enough.
Be sure to turn off the printer before attempting to clean any part of it.

Rollers seem to slip when feeding paper so the paper never comes gets printed.


The roller kit you need is RK-2100. You can do a Google search for this item. The kit contains the pickup rollers and the separation pads for both trays and also comes with the transfer roller. You can install them yourself in about 10 minutes. The roller kit is also available here.

I have an HP LaserJet 2100 printer and it prints really light on the right hand side, but prints nice and dark on the left hand side. Any suggestions on what I should be looking for to correct this?


This is usually caused by the charge roller. If you pull out your toner and look inside under where the toner goes you will see a black roller bar that goes from one side to the other, that is the charge roller. This roller is what applies the charge to the paper so the toner will stick to it before it goes into the fuser. If you roller is worn it will not supply the right amount of charge. The HP # is RG5-4164. If you can't find one locally at your printer repair shop we can ship you one, they run $11.00 plus shipping.
