3.4Document Insertion

Document edge guide

Insertion procedures may be customized to satisfy varied applications and user preferences. (See the Printer Parameters in 3.5.1).

If auto alignment is enabled, gently insert the document upper left corner toward the point where the left edge guide and the feed rollers meet. Release the document when the rollers grip it and it will be automatically aligned and inserted to the first print line.

Auto alignment may be disabled for an individual document by pressing the FUNCT key before insertion or for all documents by changing the SKEW CORRECT printer parameter. When auto alignment is disabled, the left document edge should be aligned to the left edge guide and then slid forward into the feed rollers which will insert it to the first print line.

The PAUSE printer parameter may be set to delay when the rollers activate for a few seconds or until the Akey is pressed. This allows more time to insert cumbersome documents or to train new users. With auto alignment enabled the printer should be configured for no delay.

The DOCUMENT INSERT printer parameter may be set to move the document to the last (bottommost) rather than the first printable line.

The BEGIN PRINTING printer parameter may be set to delay printing until ENTER is pressed. This allows the operator to insure that the document has inserted correctly. If not, it may be EJECTed and reinserted.
