User manual CITIZEN CLP-8301

[. . . ] This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. [. . . ] Then lower the printhead assembly fully and push down firmly on the top edge by the ribbon holders to lock in place. Place the media holder shaft onto the round notches on the media guides and media holder shaft supporting plates on both sides. Place the fanfold media on firm, level surface in the back of the printer and route it through the opening between top and lower bottom covers on the back of the printer, over the media holder shaft and platen out to the top of the printer. This printer is designed to align the center of the media (paper) with the center of the printhead, regardless of media width. refer to the scale on the tear bar for aligning media (paper) or ribbon. And for reference, the center of the gear of the media guide drive mechanism, which is located on the bottom of the printer main body, is the center of the media. To align the ribbon with the media (paper) being used, adjust the flange as follows: 1) First turn the Lock Nut on the ribbon mandrel counterclockwise, then turn the Ribbon Positioning Nut counterclockwise to move the Flange towards the center of the ribbon mandrel and to align it with the edge of the media being loaded. Referring to the scale on the tear bar, adjust the flange so that the ribbon is put in the center of the media. Check to see that the ribbon is positioned properly and fix the ribbon positioning nut by turning the lock nut clockwise. Two ribbon mandrels are used for loading ribbon; one is inserted in the supply (unused) ribbon core and the other is inserted the ribbon takeup core. Wind the ribbon from the takeup mandrel until most wrinkles are no longer visible. First insert the mandrels into the supply and takeup ribbon cores, affix a small piece of adhesive tape at the end of the ribbon and then wind the ribbon around the takeup mandrel until the tape is hidden. Finally, install the ribbon by passing it through the lower side of the printhead assembly. CAUTION Be sure to wind the ribbon sufficiently over the adhesive clear tape fastened to the end of the ribbon. Perform the following sequence; open the top cover all the way until it stops at hinges, and unlock the printhead assembly by pushing the printhead release lever and raise it until it stops and stands upright. Hold by both hands the ribbon with a length of about 300 mm (1 ft) unwound between mandrels; the left hand grips the ribbon supply mandrel and the right hand grips the takeup mandrel. Temporarily winding the ribbon with a length of about 300 mm (1 ft) unwound between mandrels around the lower, bottom side of the printhead assembly, first fit both sockets of the ribbon takeup and supply mandrels, then snap into place both knobs of the ribbon takeup and supply mandrels. Remove any slack and wrinkles by turning the knob of the ribbon takeup mandrel clockwise, making sure that the ribbon is wound evenly between two mandrels. Lower the printhead assembly with ribbon and push down firmly to lock. The ribbon tension should be adjusted as needed according to the media (paper) width to prevent ribbon from wrinkling. To increase tension torque, turn the ribbon supply mandrel (the deeper side viewed from the front of the printer) knob clockwise until the required number is obtained on the scale, while stopping the gear with a coin inserted in the slit on the ribbon mandrel support and held down. If there are smudges on the print, adjust the ribbon winding torque from the control panel. [. . . ] Clear an error with a control key (other than MODE key) or command (in case of command error) and an initial message "Ready xxxxxxxx" will be shown if data is received from the host computer (see P35, 36). Since this printer uses a thermal head and a carbon ink ribbon¤thermal paper dust etc may adhere to the printhead or other related parts. If paper dust or ribbon material adheres to the printhead, irregular printer movements, paper jams or poor print quality may occur. T herefore, be sure to clean the printhead, platen and media path periodically. [. . . ]
