Image creation control

• The image creation process starts when the drum motor /K (M17) turns on [1], though transferring each
color toner image to the transfer belt is made in the order of yellow, magenta, cyan, and black.
• After M17 turns on, the other drum motors are turned on in the order of motor /Y (M14) [2], /M (M15) [3]
and /C (M16) [4].
• The erase lamp, charging corona and developing bias of each color turns on when the corresponding drum
motor starts to rotate.
• The developing motor starts to rotate [5] after the specified time passed from the start of the writing opera-
tion [6].
• The on [6] and off [8] of writing operation corresponds to the on and off of the developing bias (AC) and the
first transfer.
• The developing motor and the toner supply motor stop and the writing operation is finished [11].
• The charging corona is deenergized and the first transfer is finished. [12].
• When the turning corona turns off [15], the DC bias supply, the erase lamp and the drum motor are
stopped. This is the end of Y toner image creating process.
• Creating toner images of the other colors is performed subsequently.
• The first transfer pressure/release motor (M119) and the second transfer pressure/release motor (M34) turn
on while creating the toner images on each drum.
• When the transfer belt is moved to the first transfer position by the M19, the V_TOP signal which triggers
the second transfer is output [7].
• The toner images on each drum are transferred to the transfer belt one by one (first transfer).
• The separation (HV/2) turns on [9] after the specified time passed from when the V_TOP signal is output.
• After the specified time passed from when the separation (HV/2) turns on, the second transfer (HV/2) turns
on [10] to transfer the complete toner image on the belt to paper (second transfer). The bias supply is
stopped [10] and second transfer cleaning is canceled.
• The second transfer operation is terminated after the specified time passed from when supplying the devel-
oping AC bias for black is stopped [13].
• After the specified time passed from when M19 stops applying pressure [14] against the transfer belt, the
bias is applied [16] and second transfer cleaning is performed.
