Zebra Printer GT800

Caution: Prepare your work area by protecting against static discharge. Your work area must be static-safe and include a properly grounded conductive cushioned mat to hold the printer and a conductive wrist strap for yourself.

Caution: Turn the printer power off and unplug the power cord before replacing the printhead.

Before following the steps in this procedure, open the printer by pulling the release latches forward then lifting the top cover.

Open the printer. Remove any transfer ribbon from the printer.

Grasp the right side of the printhead’s cover bracket and gently pull the bracket way from the printhead.

Use the printhead cover’s the left side’s short guide arm to release the printhead from the ribbon frame.

Use a Phillips screwdriver to remove the screw that holds the ground (green) wire.

Disconnect the two printhead cables from the printhead assembly by slowly and gently pulling them straight out of the connector.

Connect the two printhead cables to the printhead.

Caution: The printhead becomes hot while printing. To protect from damaging the printhead and risk of personal injury, avoid touching the printhead. Use only the cleaning pen to perform maintenance.

Clean it thoroughly with 90% medical-grade alcohol and a fiber-free cleaning swab. Let alcohol dissipate and the printer dry completely.

Use a cleaning swab to remove debris, dust or crust that has built-up on the holders, guides and media path surfaces. Use the alcohol in the cleaning swab to soak the debris to break up the adhesive.

1. Use a cleaning swab to wipe the channel that the movable media sensor slides within.

2. Wipe the ridges and inside of the printer to remove accumulated debris and dust.

3. Wipe the inside edges of both media guides (and media holders) to remove any built-up residue.

4. Wipe the front edge (black plastic) of the printhead and the printhead cover. Do not touch or clean the printhead as part of cleaning the media path!

5. Clean behind the ribbon cover (flapper). The cover swings down to operate and in this position the top side of media can contact this surface. Adhesive from the edges of label media can slowly transfer and build up on this inside surface.

6. Clean the dispenser (if installed) pinch roller and peel bar.

7. Wait one minute before closing the printer. Discard the cleaning swab after use.

The standard platen (drive roller) normally does not require cleaning. Paper and liner dust can accumulate without effecting print operations. Contaminates on the platen roller can damage the printhead or cause the media to slip or stick when printing. Adhesive, dirt, general dust, oils and other contaminates should be cleaned immediately off the platen.

Clean the platen (and media path) whenever the printer has significantly poorer performance, print quality or media handling. The platen is the print surface and drive roller for your media. If sticking or jamming continues even after cleaning, you must replace the platen.

The platen can be cleaned with a fiber-free swab (such as a Texpad swab) or a lint free, clean, damp cloth very lightly moistened with medical grade alcohol (90% pure or better).

1. Open the cover (and dispenser door). Remove media from platen area.

2. Pull the platen bearing latch release tabs to the outside of the printer. Lift and rotate the arm up and then towards the front of the printer.

3. Lift the platen out of the printer’s bottom frame.

4. Clean the platen with the alcohol moistened swab. Clean from the center out. Repeat this process until the all of the roller surface has been cleaned. If there has been heavy adhesive build-up or label jam, repeat with a new swab to remove residual contaminates.

Adhesives and oils, for example, may be thinned by the initial cleaning but not completely removed.

5. Install the platen in the printer. Discard the cleaning swabs after use - do not reuse.
