ON (SW-DOWN): Interrupts the printing currently under way and prints a new picture when you press the PRINT button during printing. OFF (SW-UP): Disregards the fact that the PRINT button is pressed during printing and continues the printing currently under way. If you press the PRINT button during printing in the OFF mode, the alarm buzzer will sound.
When loading paper • Do not fold the paper or touch the printing surface. Dust or finger prints are likely to cause poor print quality. • Before loading the paper roll, remove the label attached to the top of paper roll and pull out the first 15 to 20 cm (6 to 8 inches). The label mark is likely to cause poor print quality. Storing printouts • Avoid storing printouts in a location subject to the following. Storage of your printouts in such a place results in fading of printouts. – Store printouts in a cool and dark place (below 30°C or 86°F). We recommend storing printouts in a bag made of clay-free paper or polypropylene. – Do not store printouts in a hot or humid place. Do not leave printouts in direct sunlight or other bright places. – Do not allow any volatile organic solvent or vinyl chloride to touch printouts. Alcohol, plastic tape or film will cause the printout to fade. • Do not stack your printouts on or under a diazo copy sheet. Also do not attach the printed surface to another printed surface. The printout may become discolored. • To attach the printout to another piece of paper, use double-sided adhesive tape or water-based glue.

You cannot adjust the image once it has been captured in memory. Restore an image after adjustment by pressing the PRINT button.
Remotely Controlling the Printer
Operation
You can remotely control the printer using the RM-91 remote control unit or the foot switch connected to the REMOTE connector on the rear panel.
Maintenance
On safety
Cleaning the cabinet
• Check the operating voltage before operation. Operate the unit only with a power source specified in “Specifications”. • Stop operation immediately if any liquid or solid object falls into the cabinet. Unplug the unit and have it checked by qualified personnel. • Unplug the unit from the wall outlet if you will not be using it for a long time. Disconnect the power cord by grasping the plug. Never pull the cord itself. • Do not disassemble the cabinet. Refer servicing to qualified personnel only. • Do not touch the cutting blade of the printer. • Connect the power plug of the printer to a wall outlet with a protective earth terminal. The safety earth should be properly established.
Do not use strong solvents to clean the printer. Thinner or abrasive cleansers will damage the cabinet.
Cleaning the thermal head If the printout is dirty or white stripes appear on the printouts, clean the thermal head using the cleaning sheet supplied .
1 Press the power switch to turn on the printer.
On operation Do not turn the power off while the printer is printing. The thermal head may be damaged.
Others
Since the button on the remote control unit or foot switch functions exactly same as the PRINT button, pressing either of them during printing or copying results in an image being captured and immediately printed when DIP Switch 1 (INTERRUPT) on the rear panel is set to ON (SW-DOWN). (See page 24.)
Precautions
2 Press the OPEN button to open the door.
On the printer carriage Note
To adjust the contrast and brightness while confirming the adjusted image on the video monitor, set DIP Switch 8 (OUTPUT) to EE (SW-UP). After adjusting the contrast and brightness, be sure to reset DIP Switch 8 to THRU (SW-DOWN). Since the video signal is directly input to the video monitor without being processed by the printer when the setting is THRU, you can monitor the video signal as it is input directly from the video equipment.
To adjust the contrast You can adjust the contrast of image using the CONTR control. To make the contrast stronger, turn the CONTR control clockwise. To make the contrast weaker, turn the CONTR control counterclockwise.
Do not carry or move the printer when the paper roll is placed in the printer. Doing so may cause a malfunction.
On installation • Place the printer on a level and stable surface. If you use the printer with placed on an uneven surface, malfunction of the printer is likely to occur. • Do not install the printer near heat sources. Avoid locations near radiators or air ducts, or places subject to direct sunlight or excessive dust, humidity, mechanical shock or vibration. • Provide adequate air circulation to prevent heat buildup. Do not place the printer on surfaces such as rugs, blankets, etc., or near materials such as curtains and draperies. • If the printer is subjected to wide and sudden changes in temperature, such as when it is moved from a cold room to a warm room or when it is left in a room with a heater that tends to produce large amounts of moisture, condensation may form inside the printer. In such cases the printer will probably not work properly, and may even develop a fault if you persist in using it. If moisture or condensation forms, turn off the power and allow the printer to stand for at least one hour.

Troubleshooting
Location and Function of Parts
Troubleshooting The following troubleshooting checks will help you correct the most common problems you may encounter with your printer. Before proceeding with these trouble check, first checks that the power cord is firmly connected. Should the problem persist, unplug the printer and contact your Sony dealer or local authorized Sony service facility. Symptom
Cause/remedy
White specks on the first few printouts.
When printing with a newly inserted roll of paper, dust on the surface of the paper may cause white specks on the printouts. t Feed the paper by pressing the FEED button until clean paper appears. (page 26)
Printing does not start when you press the PRINT button.
Paper jam
The printout is dirty.
34
Others
This problem may result from the video signal input to the printer. t Change the setting of the DIP switches 6 and 7 (SCAN). (page 24) • Open the door by pressing the OPEN button, then pull the jammed paper slowly and remove it. • There is condensation inside the unit. t Moving the unit suddenly from a cold place to a warm place often results in condensation forming. In the event of condensation forming, remove the paper, turn off the power and allow the unit to stand for about one to two hours.
Cause/remedy
The printer stops printing when it continuously prints dark images. (The alarm buzzer sounds.)
This is likely to occur when the printer prints continuously 15 or more dark images. In such a case, the buzzer sounds. This is because a protective circuit guards against heat build-up in the thermal head. Stop printing for a while.
White lines or small letters on the screen are not printed clearly.
Is DIP Switch qa (INPUT) set to B & W when the input signal is a black and white signal? (page 25)
Small squares appear over the whole screen.
Is DIP Switch qa (INPUT) set to COLOR when the input signal is a color signal? (page 25)
The printout is too dark or too light.
• Is the DIP switch qs (75Ω ) set correctly? (page 25) • Is the PAPER TYPE switch in the paper tray set correctly? (page 23) • Is the GAMMA switch in the paper tray set correctly? (page 23)
The printout seems stretched or enlarged.
