Hello. My name is***** to JustAnswer. I'm reviewing your question now, and will post back with your reply momentarily.
This error may need replacement parts, but we want to check first.
Also, please keep in mind, printers are difficult to determine issues as we cannot see the machine itself.
If the troubleshooting we do doesnt resolve the issue, please respond instead of closing out to continue.
There are certain ways we can test what is causing the smudging with the hp 4250 printer. The half way test as it is referred to will help isolate between the toner cartridge or the fuser assembly of the printer. To perform a half way test with the printer, put the paper in the tray 1. Start printing and once the paper is roughly 60% inside lift the toner access lid. The hp laserjet 4250 will stop and the paper will jam underneath the toner cartridge. Pull out the toner cartridge and inspect the paper that has printed. The toner has not yet been fused to the paper by the printer’s fuser, so you will just want to look at the page vs pull it out. If you notice smudges on the page then you can be certain the toner is smudging the print. If you do not see smudged print, then you can be certain the 4250 fuser unit is smudging the print.
Please follow the guide below and it will direct you to narrow down the issue:
Please respond when done with results.
