APPENDIX C - Tips & Hints

Power ON Sequence

Power On TowerFeed first!

When powering on the printer, it will scan its option bus for available options. In case TowerFeed is not ready at that point of time, the printer will not activate its support and not add this option to its configuration.

Printing on the wrong Paper

Why doesn't it print from the tray I selected?

If a selected Tray # does not contain the paper size assigned for the print job, the printer might look for other trays containing the demanded paper size, and if this is available (and with the same Paper Type as Tray #), it will pull paper from there.

The 3 Rules for Correct Paper Selection

1.Assign a different Paper Type to every Tray # by using the printers control panel.

You may assign the same Paper Type to two or more tray numbers only if these trays all contain the same Paper Type.

2.Make sure that you select the correct Paper Size for the selected Tray #.

The selected Paper Size in the application software must be the same as the size of the selected Tray #.

3.Select paper within your application by Paper Type or by Tray #.

If a tray containing the selected Paper Type runs out of paper, the printer will pull paper from another tray only if it has the same paper Size and Type.

Paper Control and Selection

Selection Criteria

The HP LaserJet offers various possibilities to select paper by offering three selection parameters:

•Paper Size

•Paper Source (Tray number)

•Paper Type

The selection criteria differ in their priorities and can be changed using the respective printer utility software.

Paper Types

The Paper Type is a selection criteria which can be used to name trays and to distinguish between different paper types within a given paper size. The HP LaserJet offers 10 predefined Paper Types: Bond, Cardstock, Color, Letterhead, Plain, Preprinted, Prepunched, Recycled, Rough and Transparency.

Default Paper Type

Without a specific paper type assigned to a tray, PLAIN becomes the default paper type. Without a specific paper source selection in a document, the printer will pull paper from a paper source with the paper type PLAIN.

Assigning a Paper Type to a Tray

Please refer to the section INSTALLATION – Printer Panel Settings – Paper Type Assignment of this manual or to the printer's manual for more details on how to assign a paper type to a tray.
