Chapter 2 2.2 Basic Sequence 2.2.1 Basic Sequence 0011-3541 The machine's sequence of operation is controlled by the CPU on the image processor PCB and the CPU on the DC controller PCB. The following figure shows the sequential flow, and table provides descriptions of the periods involved. Power ON or The left cover is closed or Return from ESS mode Wait Standby End of printing If a print command is received during last rotation Initial rotation Print Last rotation Period WAIT (wait) STBY (standby) INTR (initial rotation) PRINT (print) LSTR (last rotation) F-2-5 T-2-1 If continuous printing is selected Definition Purpose Remarks From when the power is turned on The machine's mechanical and electrical until the main motor is turned on and states are checked. stopped. A check is made on the presence/absence of a cartridge and for paper remaining inside the machine. The machine also shifts the WAIT state when the left cover is closed while power is on, or after returning from ESS mode. After the end of The machine is ready for a print command. WAIT, unit the Start key is pressed. After a press on the Start key, until the leading edge is detected by the paper leading edge sensor. The machine starts up process conditions and The fixing heater is subjected to temperature contro (start-up picks up paper for printing. temperature control, paper passage temperature control); scanner rotation speed adjustment and ATVC control are executed. After the registration sensor detects the leading edge of paper, until the delivery sensor detects the trailing edge of paper. The DC controller PCB generates the BD0* signal, and the image processor PCB sends VD0* signal and VD0 signal, thereby forming a latent image on the photosensitive drum and turning it into a toner image. From when printing ends until the main motor stops. The drum surface is made free of potential and the transfer charging roller is cleaned. After last rotation, the machine shifts to standby to wait for a print command, in response to which it immediately shifts to initial rotation. 2-6
