HP Deskjet 3930 Color Inkjet Printer - Manual (Page 39)

Maintain the printer body
Because the printer ejects ink onto the paper in a fine mist, ink smudges will
eventually appear on the printer case and adjacent surfaces. To remove smudges,
stains, or dried ink from the exterior of the printer, use a soft cloth moistened with
water.
When cleaning the printer, keep these tips in mind:
●
Do not clean the interior of the printer. Keep all fluids away from the interior.
● Do not use household cleaners or detergent. If a household cleaner or detergent
has been used on the printer, wipe the exterior surfaces with a soft cloth
moistened with water.
● Do not lubricate the support rod that the print cartridge cradle uses to slide back
and forth. Noise is normal when the cradle moves back and forth.

Surface Remedy

on the print cartridge contacts.
