Cleaning the printer

Cleaning the printer cabinet

Clean the outside cabinet as needed, using any household cleaner made for plastics. You may want to test a

small unseen area rst. Wipe the paper compartment with a clean, damp cloth. The cabinet materials and

nish are durable and can tolerate cleaning solutions, lubricants, fuels, cooking oils, and ultraviolet light.

Cleaning the thermal print head

CAUTION: Don’t touch the thermal print head, as this can cause burns.

IMPORTANT: Do not attempt to clean the inside of the printer with any spray cleaner. Do not try to clean the

thermal print head (except as recommended) or allow any spray to come in contact with it. This may damage

the internal electronics or thermal print head. If the print head appears dirty, wipe it with isopropyl (rubbing)

alcohol on a cotton swab or alcohol pen. Do not use the rubbing alcohol to clean any other parts of the printer

because it may cause damage to the printer.

NOTE: The thermal print head does not normally require cleaning when recommended paper grades are

used. If nonrecommended paper is used over an extended period, attempting to clean the print head will have

little eect on the print quality and could cause jamming and other damage to the printer, voiding the

warranty.

If spotty or light printing problems persist after cleaning the thermal print head, the thermal print mechanism

may need to be replaced.

Cleaning out paper dust

HP recommends that you remove paper dust from your printer approximately every six months, using canned

air or some other kind of fan to blow the dust out of the printer.

Cleaning the MICR

HP recommends that you clean the contact image sensor approximately every six months, using a cotton

swab and rubbing alcohol.

Clearing paper jams

Clearing a receipt paper jam

To clear a receipt paper jam:

1. There is a lip on each side of the receipt cover, near where the receipt emerges. Using one nger from

each hand, rmly raise the receipt cover.

2. Draw the crumpled portion of the paper out of the printer until the smooth portion extends a few inches

over the cabinet front.

3. When there is paper jammed into the roller in the receipt cover, draw the paper out from the roller.

NOTE: The paper must unroll from the bottom of the roll to ensure that the image prints.

4. While holding the smooth paper over the front of the cabinet, rmly press the receipt cover closed.

5. Remove the excess paper by tearing it against the tear-o blade.
