5.2.5 Print

After sensing the transfer belt home position the following tasks are performed:
Send Psync signal to controller
Operates virtual timer for each color(Vdata)
Forms latent image on drum
Supplies toner on OPC drum
Transfers image to transfer belt (T1 )
Picks paper
Transfers image to paper (T2)
1) Check Transfer Belt Home (Treated by Home interrupt every 3 seconds):
a. Transfer belt home sensing
b. If test mode is selected, a test pattern is printed.
c. A counter value is set up that addresses the timing to turn on page sync.
d. The virtual timer for each color (Y, M, C, and K) is set up.
e. If home is not detected every 3 seconds, an error is reported on the control panel.
2) Paper Path Printing
a.
Paper is picked from Tray 1, Tray 2, or MPT
b. Control paper path
Paper pick stops when the leading edge of the paper reaches the feed sensor.
If the leading edge doesn't reach the feed sensor, an error is reported.
While transferring the last color to the transfer belt, transports the paper.
Checks if the paper reaches the exit sensor in the specified amount of time, otherwise an error is reported.
Checks paper passing the exit sensor.
c. Jam check
Check paper reaching and passing the feed and exit sensors, otherwise an error is reported.
d. Duplex control
After passing the exit sensor, the duplex clutch is engaged to mechanically change the direction of the
paper in order to print the other side.
e. Printing sequence for each color
Uses a virtual timer for printing the colors in the correct sequence. (Yellow, Magenta, Cyan, Black)
A virtual timer is an algorithm for creating regular action at fixed time intervals. The standard setting is for a
5 msc timer interrupt.
