HP4350 dtn Laserjet printer

I have this dual tray printer and when I print legal size paper that has many lines in it (HUD) the lines on the paper are not clean. If I print letter size the lines are fine. I just changed the toner (built in drum), but the previous toners have done the same thing. Any ideas to what the cause is and is there a way to fix it? Thank you.

I don't know if this will help or sole the problem. If you have dual printer drawers, don't forget to reset those settings after you're done

”Turn the Printer on.
”Press and hold down the checkmark (Select) button while the memory is counting. The memory starts counting at 000MB immediately after you turn the power on. (Note: on laserjets 4200, 4300, 9000 you can hold down the checkmark button as you turn the power on, then wait for the three LEDs to illuminate. On the laserjets 4250, 4350, and 2400 series you need to wait until you turn the power on and the memory starts counting before you hold the checkmark button.)
”Continue to hold down the checkmark (Select) button until all three LEDs are illuminated.
”Release the checkmark (Select) button.
”Press the up arrow (Navigation) button until the message New Maintenance Kit appears on the control panel display.
”Press the checkmark button once.
”A message New Maintenance will appear in the control panel display and the printer will reset.
is will help. However, give it a try.

Re: HP4350 dtn Laserjet printer- All that does is reset the

counter to 0 for the next "perform maintenance"

I have this same printer, but without duplex. Do you mean the lines are fuzzy? What dpi setting are you printing at?

The lines are fuzzy, but only on legal size. I am not sure what the dpi settings are. I will check when I get back to it. What should they be set at?

Mine is set at 300 dpi and I do get fuzzy lines when the file has been scanned poorly. For those particular files I set the dpi to 600. When I'm finished printing those particular files, I set it back to 300 dpi. I have not noticed it happening with legal size as opposed to letter size - for me it seems to strictly be a scan quality issue, and I can tell it's poorly scanned by looking at the file on my computer screeen.

Is it all legal sized pages? I had a similar situation the other day on some pages on my old 4250. Don't think it was the printer though. Wonder if the was the new PDF version. It went away. Also it was a genuine HP cartridge
