EPSON Stylus PHOTO 2100/2200 Revision B 2.2.7.1 Cutter Initialization Sequence When the Cutter is fitted, the cutter initialization sequence is executed if the printer has confirmed that the Cutter has been fitted (the Power switch blinks about 5 seconds). The cutter initialization sequence is an operation performed to securely put the Cutter blade in a standby position detected by the right HP sensor if the Cutter blade is not detected by the right HP sensor. In the initialization sequence, if the Cutter blade does not reach the HP sensor (right or left) within 3 seconds in either rightward or leftward Cutter motion, Cutter position error occurs. If the Cutter blade is in the right HP sensor position when the Cutter is fitted, the initialization operation is not performed specifically. In Cutter operation, Cutter position error or Cutter jam error is detected. Differences between these errors are as follows. ! Cutter jam error If the Cutter blade does not reach the left or right HP sensor, the Cutter blade is returned to the HP sensor located in the motion starting position (right HP sensor). At this time, Cutter jam error occurs if the Cutter blade can return to the HP sensor position located in the motion starting position within 3 seconds. ! Cutter position error If the Cutter blade does not reach the left or right HP sensor, the Cutter blade is returned to the HP sensor located in the motion starting position (right HP sensor). At this time, Cutter position error occurs if the Cutter blade cannot return to the HP sensor position located in the motion starting position within 3 seconds. Paper cutting by the Cutter consists of the basic cutting sequences 1 and 2. The basic sequence 1 means movement from the right HP sensor to the left HP sensor. At this time, as soon as the Cutter blade starts moving from the right HP sensor, the timer starts. If the left HP sensor does not detect the Cutter blade within 3 seconds, the cutter initialization sequence is executed and then Cutter jam error or Cutter position error occurs. The basic cutting sequence 2 means movement from the left HP sensor to the right HP sensor. At this time, if the Cutter blade cannot move from the left HP sensor to the right HP sensor within 3 seconds, Cutter position error occurs. 2.2.7.2 Cutter Self-cleaning In the Cutter unit, there is a plate (plate where the paper print surface comes into contact) above the Paper hold-down flap. This sequence indicates the operation performed to hold down and remove the ink, which may stick to that plate, with the leading edge of the fed roll paper. Since the Cutter blade must be operated left-to-right to operate the Paper hold-down flap, the Cutter blade generates operating noise during cutter self-CL when the roll paper is fed. 2.2.7.3 Cutter Cleaning (Driver Side) This sequence is executed on the driver side. By cutting the roll paper three times (T.B.D.) at intervals of 6cm, the ink that may stick to the Cutter blade is removed to clean the Cutter blade. OPERATING PRINCIPLES Printer Mechanism 64
