APPENDIX G - TowerTray Selftest

TowerTray Selftest Feature

The TowerTray selftest feature allows to test the TowerTray unit independently from any printer and computer. With this test you can check for correct paper feeding (horizontal position, skew, jam behavior).

Note:

To perform a TowerTray selftest, remove the printer's paper cassette.

Follow the following steps:

•Power-off TowerTray.

•Open all TowerTray Trays (approx. 10 cm).

•Power-on TowerTray.

•Wait until you hear a short beep followed by the clicking of the solenoid activation in every module, and finally the spinning of the motor (approx. 2 sec).

•Close the top-most TowerTray tray. After a second a sheet will be fed from this drawer. You now can mark the position of the left border of the sheet on the TowerTray top cover (reference for horizontal paper position).

•Pull out the sheet from its waiting position. TowerTray will automatically feed a next sheet. You now can compare the position of the left border of the next sheet. If it moves up straight in the same position, this is ok. (In case the left position would be different, or moving from left to right (or vice-versa), this might indicate a problem in either the tray, the unit (module) or the paper loading.)

•To test the next lower tray, close that tray before removing the sheet from its waiting position. Now TowerTray will feed the sheet from that next lower tray. (TowerTray will always feed the next sheet from its lowest closed tray.)

•To revert to normal operation, power-off and on TowerTray again with all trays closed. TowerTray will respond with a short 'Reset' beep that it is ready again.

In case error conditions are showing up which are depending on a specific TowerTray tray, you can swap trays to find out whether a problem exists with the tray itself or whether a specific module is the cause. Please note, that the top tray (part nr. 206012) MUST always be the topmost tray of TowerTray.
