HP 4250 print fades on left and right sides after five sheets

Well lets start with DISREGARD ALL THE ABOVE BULL in the above brainless clarification request first noted. Here's a little good advice for you from a 14 year veteran printer tech.

Lets start with the cheapest and easiest moving to the more difficult or more expensive. Your problem can be caused by a few differnt things.

Print a configuration page (on the printer menu press check button, scroll to info menu, press check, scroll to print configuration, press check. Once you have the look for the page count on the page.

Try fresh good paper from a sealed ****. If your paper has picked up moisture this will show up as light or uneven print.

Next if the printer is over 100K page count, replace the transfer roller (foam roller inside printer under the toner cartridge). Lets try cleaning it first if your under 100K or to see if it improves at all. Any improvement will verify the transfer roller as bad. Review the photo below as it shows the transfer roller end inside the printer. The screwdriver is showing where the release white clips are (two). Press the tabs and lift the left side. The right will come out of the hole socket on its own but note where the hole on the right is for replacement. Try not handling the roller with your bare hands any more than you must as oil from your hands can cause slight imaging defects if your hands are sweaty or damp.


Using a clean rag (like t-shirt material) dampened (not soaking) with 99% alcohol (not 70%) lets clean the roller. Gently but firmly scrub the talc and paper dust buil-up from the roller. Once you've removed the build up it should return to a dark grey color. Let the 99% alcohol dry (5 minutes or so)and reinstall.

Try printing again. If the problem is solved your done. If not and it has improved, you will need a new transfer roller. They are available on Ebay much cheaper than from a dealer. The part number to search for is RM1-0343. Here's a link to ebay for one at around $20.00 landed.

If the problem is the same, your problem is more than likely a dirty laser scanner lense. You'll need to remove the covers from the printer to accomplish this. The laser scanner can be located under the top cover. It's the larger black box on the top side of the printer. Once the scanner has been located, remove the top cover. DO NOT TOUCH THE MULTI SIDED SPINNING MIRROR TO THE REAR OF THE SCANNER. You will be cleaning the clear lenses and mirror towards the front. You clean this gently with a CLEAN and DRY Q-tip. Use a few Q-tips rather than re-applying a dirty one. Heck they are cheap!

Re-assemble the printer and try printing again. One of the steps above should resolve your issue. I am enclosing a link to a free service manual for your printer to help you through the disassembly and in the rare case that your issue remains.

If the spacing between dots are the same, then you have a dirty or bad roller. If you never had this problem prior to installing the new toner cartridge, then I would suspect you have a bad one. Try a different toner.

When installing new cartridges, it's always a great idea to perform a cleaning and recalibration of the machine. Below are the steps needed to do just such a task. You may want to print these out or save them somewhere for future reference as well. They are directly from the HP website.

Make sure the transfer roller is clean and making good contact.

Have you check the teflon at the heater? have you clean the reflector of laser? Try that.
