EPSON Stylus PHOTO 2100/2200 Revision B 2.2.3.4 Manual Paper Feeding Mechanism (Board Paper) To enable direct printing onto thick paper and CD-R label, this product has the mechanism to feed paper from the printer front and rear manually. Move the Release lever to the farthest position, insert thick paper from the rear manual feed slot until its leading edge reaches a position about 1cm from the PF/Driven roller, and set the Release lever in the thick paper mode. When the PE sensor detects the paper after the above Release lever has been operated, pressing the Paper feed switch causes the PW sensor to detect the leading edge of the paper and the printer to perform paper locating control and enter the standby status. 2.2.3.5 Roll Paper Feeding Since panel operation in the roll paper mode differs from the above operation, the differences of panel operation after roll paper feeding will be described. 1. When roll paper is fed with the Release lever not in the release position, the PE sensor detects the paper, and after 2 seconds has elapsed, the paper is fed. 2. The PW sensor check for the leading edge of the paper, and if it detects the paper, the printer operates in the cutter self-cleaning mode. 3. The printer back-feeds the paper to the paper print starting position. As explained above, when roll paper is inserted from the Roll paper feeding guide to the paper feeding position of the PE sensor, paper is automatically fed and back-fed to the print starting position. At this time, panel switch operation is invalid (since 02 is written to 3F in the EEPROM), and the definitions of the panel operation and Paper feed switch differ between cut sheets and roll paper. When roll paper is fed, 02 is written to the EEPROM 3F area, but when roll paper print data is received from the PC, 01 is written to the 3F area. Panel switch operation differs as described below between when 02 is written to the 3F area and when 01 is written there. ! When 02 is written Pressing the Roll paper cut switch for more than 3 seconds back-feeds the leading edge of the roll paper to the PE sensor (the Paper LED blinks). When the roll paper is removed from under the PE sensor in this state, paper is fed from the ASF. ! When 01 is written and cutter is fitted When the data from the photo quicker is "No auto cut", pressing the Roll paper cut switch after end of printing feeds the separation position in the print data to the roll paper cut position and returns the leading edge of the paper to the print starting position after paper cutting. When the data from the photo quicker is "Standard 1 cut" or "Specific 2 cuts", the roll paper is cut automatically at every separation of the print data, and the leading edge of the paper is then returned to the print starting position.
