2. Sheet input
Once the paper is in the intermediate shaft area, the drive roller is rotated, impelling the intermediate
shaft through the right gear module, pushing the sheet towards the inside of the printer, so that it will be
grabbed by the drive roller and main printer pinch system, proceeding with the standard paper drive
motion (as with roll paper).
NOTE: The printer considers the load successful if, after the picking and sheet input procedures, the
sheet is detected by the printer's Paper Sensor. Hence, a correct function of the Paper Sensor is
required also for the accessory tray loading action.
NOTE: It is possible to reproduce the picking and loading motions by extracting the Multi-Sheet Tray
and rotating the gears with the hand, to validate module performance and troubleshoot any possible
mechanical issues.
NOTE: Different elements of the Multi-Sheet Tray are not serviceable, the whole module requires
replacement in case of failure.
Electronics
Both the encoder and motor-drive system are managed by the Bundle PCA located on the right-hand
side of the printer.
