If the sprocket pins do not engage with the sprocket holes, move the paper holder to fit. Put down the paper holder cover and push the paper release lever to OPEN. e. Turn the platen knob and set the paper to the print start position. Note 1) After the paper setting, press the paper advance key and feed the paper for one line. (Thi

  • Commodore MPS-803, 2-12 3. Performing the Printer Power On Test You are now ready to proceed with the power-on part of the checkout. (1) Turn on the AC power to your computer and verify that is working correctly. (2) To turn on the power to the printer, press the rocker switch at the side of the printer so that the white dot is visible. In response to the application of AC power, POWER light in the PAPER ADVANCE switch should be lit and the printer's microprocessor should move the print head all the way to the right, then to the home position at the far left. If this does not happen (and that'â highly unlikely), turn off both machines, check all connections and try again. If

  • Commodore MPS-803, 3-5 (b) Paper release mechanism By setting the release lever to OPEN, the paper release shaft turns through the gear. The roller retaining spring is released and the platen detaches from the PF roller assy. (PAPER RELEASE CONDITION) In this condition, paper position can be corrected. (c) PE switch PE switch detects the presence of the printing paper. When the paper is being set, the PE switch actuator is pushed down for printer operation. When the paper has run out, the PE switch actuator moves away upward to detect the PE condition. Then the ERROR status turns on and the printer stops. (Paper Em

  • 3-2 Operating principle 1. Printing mechanism The impact wire dot system is employed Print head contains 8 solenoids circularly positioned on the core frame, armature print wires operated by the solenoids and wire guides. The 8 print wires are precision located by the guides on top. Printing is executed when the carriage travels at the printing speed, the character genera

  • Commodore MPS-803, 3-13 9. Carriage Driver Circuit CPU CR motor is a step motor of PM type. When stopped, CRPLS is set to 'HIGH' and is powered by +9V source for holding. Operated by 2-2 phase excitation. l"/60 per 1 step with the operating speed at 360pps. The carriage reverses when the excitation sequence for the LF motor mentioned before is applied. Basically performs 8-pulse SLEW UP/DOWN. While running CRPLiJ is set to 'LOW' and the motor is supplied with +24V power. Driver IC is same as that for paper feeding. Pica size takes 1"/10 and is comprised of 6 steps.

(3) Pull off the PE/EP HARNESS ASSY and connectors of the CR motor and LF motor. Then the FRAME UNIT can be separated from the BOTTOM COVER. Note) Pull off the connectors by holding the connector body. Do not hold the lead wires. (Attachment) (1) Perform attachment by following the reverse of the detachment procedures. Note) Use care not to catch the lead wires during attachment.
