Refer servicing to qu alif[...]

To avoid the risk of electric shock: ● Do not attempt to disma ntle the drying and curi ng modules or the electrical control cabinet. ● Do not remove or open any othe r closed system covers or plugs. ● Do not insert objects thro ugh slots in the printer. NOTE: A blown fuse may indicate malfunctioning electrical circuits within t he system. Ca[...]

● Avoid standing close to the fans, which could cause injury and could also affect print quality (by obstructing the air flow). ● Do not touch gears or movi ng rolls during printing. Heavy substrate hazard Special care must be t aken to avoid persona l injury when han dling heavy subst rates. ● Handling heavy sub strate rolls may require more[...]

Label Explanation See installation instructions before connecting to the supply. Ensure that the input voltage is within the printer's rated voltage range. The printer requires two dedicated lines, each protected by a branch circuit breaker according to the ratin g of the wall socket outlet. Use only earthed mains outlets and the power cords s[...]

● Accurate and consistent color reprod uction with automatic color calibration (built-in spectrophotometer) ● ENERGY STAR® qualified product To send print jobs to your printer, you will need Raster Image Processor (RIP) software, which should be run on a separate computer.

Check the ink quantity Check the p rinted chart in the following ways. 1. Too much ink: There are several possib le symptoms of this problem. ● The last two or three scales of the plot look the same. ● Vertical banding. ● Horizontal ba nding. ENWW Add a new subst rate type 37 Handle the substrate[...]

● Coalescence, grain. Try reducing the amount of ink in your RIP software, then reprint the chart and check again. Also consider the follo wing tips. ● You may have chosen a substrate preset that uses more ink than your substrate all ows. Consult the substrate vendor's Web site and HP's Web site for the latest substrate prese ts and i[...]

Faster printing The obvious way to increase speed is to reduce the number of print passes, alth ough this will tend to reduce print quality . Bear in mind the fo llowing consid erations. ● With fewer than 10 pa sses, you may see an increase i n grain. ● With 4 or 6 passes, the printer is more sensitive to substrat e advance problems. ● With 4[...]

5 Handle the ink system Ink system components Ink cartridges The printer's six ink cartridges provide magenta, ligh t magenta, black, yel low, light cyan and cyan ink to the printheads.
