SECTION 2

INSTALLING THE PRINTER

Envelope Printing Attachment Kit

The Envelope Printing Attachment Kit (42-900-55) is included with the printer.

Kit Includes:

• Head Media Guide (1)

• Left-hand (large) PPS Spacer (1)

• Right-hand (small) PPS Spacer (1)

CAUTION: Do NOT use “PPS Spacers” with earlier style Envelope Printing Attachments (Head Media

Guides) that did not come with Spacers. If this rule is not followed, significant loss of print quality will

result.

The Head Media Guide is used to flatten the media, as it enters under the printhead; to help reduce media

contact with the printhead.

The PPS Spacers are used to increase the gap between the printhead and the platen; to further reduce the

chance for media contact with the printhead.

The most common head to media contact areas are the high points (bows, bends, flaps) on the media and

the trailing edge of the media, since there is no control over the media lifting, once it leaves the Head

Media Guide.

If the media makes contact with the printhead this may result in:

- Scuff Marks - black streaks deposited on surface of media

- Smearing/Smudging of wet image, which can also deposit additional ink on the printhead surface;

increasing the chance for additional scuff marks.

See section titled “Troubleshooting Guide” for more info on scuff marks and how to reduce.

Installing/Removing the Head Media Guide

This item is normally pre-installed in the printer. In general the Head Media Guide can be used at all times.

However if you are primarily printing on thin, flat stock and you are encountering print quality issues

(image distortions, image not as sharp as expected); you can remove the Head Media Guide to see if this

has any effect.
