PREFACE
Congratulations! You selected TowerTray, a modular expandable, sheet feeder specifically designed in
collaboration with Hewlett-Packard, USA, to extend the paper handling capabilities of the HP LaserJet 4200 / 4300
/ 4250 / 4350.
The TowerTray Option offers new possibilities. You can
• select from up to 9 different paper types directly from your PC.
• print extra copies instead of going to the copier to make copies. You get better copies and you can
color code copies of documents on color paper to help clearly identify a copy. The color already defines the
addressee and you will save the marking of the copies.
• realize an attractive alternative to the multi-part forms printed on conventional impact printers. You
will get better copies, raise the flexibility and you will save money on expensive preprints and chemical
papers.
We encourage you to read this manual carefully to ensure correct installation and reliable operation.
While installing TowerTray, or whenever an unclear situation arises, please also consult the user's manuals of your
HP LaserJet 4200 / 4300 / 4250 / 4350, your computer system, your application software and your network
software.
The name TowerTray is generic to the TowerTray family of automatic sheet feeders and is used throughout this
manual.
TowerTray and additional trays for TowerTray (Middle Trays) have these part number assignements:
TowerTray 221000 ⇒Part No.: 221000
Additional Trays ⇒Part No.: 206011
(*only for TowerTray use)
* Additional TowerTray trays do work only within the TowerTray setup. For use within the HP LaserJet setup do
order the original HP trays via your prefered Hewlett-Packard source. See page 8: Array of Trays and page 17:
Original HP 500-Sheet Tray.
A plate showing type, designation and serial number is located next to the power inlet of the TowerTray. Please
refer to this designation and the serial number whenever you call your service organization.

INSTALLATION
Position and Connect Printer
Warning:
The printer may weigh up to 34 kilograms (75 pounds). Enlist the
help of a second person to lift the unit. To prevent back strain or
injury, bend your knees when lifting the unit.
Note:
To meet requirements for absolute toppling security TowerTray has
to be equipped with the supplied tilt protection (see picture). Also,
never open more than one tray at the same time.
Note for HP LaserJet 4250 and 4350 users:
If you are using more than 2 additional HP Trays, then the
TowerTray / HP LaserJet unit has to be fixed to a building wall. To
do so, please refer to page 10 of this manual.
• Carefully lift the laser printer onto TowerTray. Make sure you
utilize the locking mechanism on the tray’s and printer’s left side.
Arrangement of trays: The TowerTray Unit can only operate with TowerTray trays where-
as the HP LaserJet Unit can only operate with original HP trays.
Therefore it is essential not to mix TowerTray trays with the original
HP trays – TowerTray trays are easily distinguished by the
TowerTray Sticker on it’s front panel.
Note: The TowerTray Unit can consist of up to four trays (one
Bottom, two middle and one Top tray) .
Data Connection
Without Stacker
Connect printer and TowerTray with the data cable (see picture):
one end with the printer and the other end with TowerTray. Use the
provided Adapter as a intermediate piece (see picture next page).
Caution:
Only move TowerTray to another place with drawers closed and
without printer on top to avoid hazard of toppling. Do not roll the
TowerTray with more than 4 trays on top – remove any surplus
trays. Drawers need to be secured against unintentional opening.
