Important Operating Notes

◆Store media and ink in an area with similar temperature and humidity conditions as the printer.

◆Locate the printer close enough to the print server (RIP) so that they can be connected with the required cable.

◆Locate the printer on a flat, level floor.

◆Locate the printer where its normal operating noise will not disturb quiet work areas.

◆DO NOT install the printer near humidifiers, refrigerators, fans, water faucets, heaters or similar equipment.

◆DO NOT install the printer in areas where the temperature changes abruptly, such as near air conditioners or in the path of direct sunlight.

◆DO NOT expose the printer to flames or dust.

◆DO NOT POWER DOWN THE PRINTER. Constant vacuum at the printheads is required to prevent ink from flowing from the printheads when not printing, even when the printheads are capped. If the printer must be powered down for ship- ping, empty and cap the printheads (See “Extended Power Down and Restart” on page 5-21) or apply auxiliary 24 volt power (see “Connecting to Power” on page 1-22).

◆If the printer has been idle for more than several minutes, press the Prime Bars button on the printer control panel to check for missing inkjets. To recover missing inkjets, see “Checking Jet Health” on page 3-6.

◆If the printer will be idle for more than one hour, cap the printheads to conserve ink. When the printheads are uncapped and the printer is not printing, the printheads periodically expel a small amount of ink into the excess ink reservoir to keep them working. (“Capping the Printheads” on page 3-11 for instructions.)

◆Refill the ink and cleaning solvent reservoirs only when the Ready-for-Refill LED is on. Refill only with an entire bottle of ColorSpan SolaChrome HR ink or cleaning solvent, and replace the profiler. USE OF OTHER INKS AND CLEANING SOLVENTS COULD DAMAGE THE PRINTER, WILL REQUIRE A SERVICE CALL, AND WILL VOID THE WARRANTY. (“Refilling Ink” on page 3-9.)

◆To wipe the printheads, use only ColorSpan cleaning solvent applied with a 100% polyester Class 100 cleanroom wipe. (See “Cleaning Clogged Ink Jets” on page 5-8 for instruc- tions.) DO NOT USE ISOPROYPL ALCOHOL.
