Chapter 3

If print quality does not improve after cleaning the print 
nozzles (see page 25), you may need to wipe the print nozzles. 
Refer to the “Troubleshooting: Print Quality” section of the 
printer driver Help. For help accessing the printer driver Help, 
see page 6.

To ensure the longest life from your print cartridge and 
optimum performance from your printer:

• Keep a new print cartridge in its packaging until you are ready 

to install it.

• Do not remove a print cartridge from the printer except to 

replace, clean, or store it in an air-tight container. The print 
cartridge does not print correctly if removed from the printer 
and left exposed for an extended period of time.

• If a print cartridge runs out of ink, leave the empty cartridge in 

the printer until you are ready to replace it. Printing with only 
one of the print cartridges in the printer may cause printer 
problems.

Lexmark’s printer warranty does not cover repair of failures or 
damage caused by a refilled cartridge. Lexmark does not 
recommend use of refilled cartridges. Refilling cartridges can 
affect print quality and cause damage to the printer. For best 
results, use Lexmark supplies.
