Printer case exterior

Inkjet printers print by spraying a fine mist of ink from the print head onto the paper. In

some situations, small amounts of ink from the printing process may be deposited on

the printer case and become visible over time. If this situation occurs, the exterior of the

printer can be clean with a soft cloth moistened with water to remove ink deposits, dust,

smudges, and fingerprints (see Figure 1 below). A mild detergent may be used if

necessary on the exterior. Do not use harsh household cleaners as they may damage

the finish on the printer case.

Printer interior

All Inkjet printers produce a small amount of ink residue that may build up inside the

printer's case. This is normal. There is no need to clean this residue. Platen cleaners or

alcohol may damage the HP Deskjet printer and should not be used. Cleaning the

interior of the printer should be limited to cleaning only the print cartridges. Do not clean

anything else inside the printer unless specifically instructed to do so. Keep all liquids

away from the inside of the printer.

CAUTION: Do not clean or lubricate the carriage rod. Cleaning or lubricating the

rod may reduce its life. The ink present on the rod will not hinder the operation of

the product.

NOTE: The carriage rod is the shaft inside the printer that the print cartridges move

back and forth on.

Accumulations of paper or lint should be carefully removed by brushing the loosematerial onto a cloth or by using a small computer vacuum cleaner.

Cleaning the HP Inkjet print cartridges can improve the quality of printing. If a printed

page is missing lines or dots, perform the steps detailed in the "Correcting missing lines

or dots" (click here) section of this document below.

If a printed page has streaks of ink on it,click hereto skip to the steps detailed in the

Eliminating ink streaks

If the HP Deskjet 900c series printer is used in a dusty environment, ink streaks may

result due to a small accumulation of debris inside the printer.

This debris can include dust, hair, carpet, or clothing fibers. Ink streaking is easily

prevented or corrected by cleaning two areas of the HP Deskjet 900c series printer:

The HP Inkjet print cartridges.

The HP Inkjet print cartridge cradle.

Materials needed

Before starting, ensure that the following materials available:

Cotton swabs or any soft material that will not come apart or leave fibers (for

example, a piece of clean cotton cloth, such as a handkerchief).

Distilled, filtered, or bottled water (tap water may contain contaminants that can

damage the HP Inkjet print cartridges).

Scrap paper or paper towels to set the HP Inkjet print cartridges on.
