Possible cause Recommended action(s)
The customer is printing on the
envelope seams. (Printing on an
envelope seam can cause a
background-scatter problem.)
Move the text to an area that has no
seams.
The toner-density setting is wrong. Open the print-quality menu at the
control panel and adjust the toner-
density setting. See Print-quality
submenu. Make sure that EconoMode
is off.
The high-transfer setting is turned off. Open the print-quality menu at the
control panel (see
Print-quality
submenu). Select OPTIMIZE and set
HIGH TRANSFER=ON.
The print cartridge is defective. Replace the print cartridge.
The high-voltage connector springs are
dirty or damaged.
The high-voltage connector springs
protrude into the print cartridge cavity.

Table 7-26 Loose toner or toner smear
Possible cause Recommended action(s)
The interior of the printer is dirty. 1 Print a few more pages and see if
the problem corrects itself.
2 Clean the inside of the printer (see
chapter 4)
3 Process a printer cleaning page.
See
Running the cleaning page
manually.
The fuser roller is dirty. Process a cleaning page (see Running
the cleaning page manually). Several
pages might be required if the fuser is
very dirty.
The media surface is too smooth or too
rough for toner adhesion.
Use media that meets
HP specifications (see the HP LaserJet
Printer Family Paper Specification
Guide).
The static-eliminator teeth (just beyond
the transfer roller) are contaminated or
are not grounded, which allows a static
charge to remain on the page.
Clean the static-eliminator teeth by
using a small brush or compressed air.
Replace the assembly if it is damaged.
