4 Handle the substrate Overview You can print on a wide variety of printing materia ls, a ll of which are referred to in this guide as substrates. Use substrate Choosing the correct substrate for your ne eds is an essential step in ensuring good print quality.
CAUTION: Remo ving the substrate from the printer ma n ually without using the front pane l could damage the printer. Do thi s only when necessary to clear a substrate jam.
3. Remove the first end of the spindle from the right side of the printer, and then move the spindle to the right in order to extract the ot her e nd. Do not insert your finger s into the spindle supp orts during the removal process. The spindle h as a stop at each end to keep the ro ll in position.
6. Rest the roll of substra te that you want to load on the lo ading table. If the roll is long and heavy, you may need two p eople to handle it. 7. Slide the spindle into the roll. 8. The right stop of the spindle has two positions: one for rolls of the printer' s maximum width, and another for narrower rolls.
9. Put the blue stop on to the u pper end of the spindl e, and push it towards the end of the roll. 10. Slide the lever-lock to the locked position. 11. Lift the loading table to ea se the spindle into th e printer. CAUTION : To avoid trapping your fingers, do not push the roll with your hands.
TIP: To load a roll of textile material, cut a strip of another substra te of a similar width to the te xtile and around 0.5 m in leng th. Polyester (b acklit) substrates a re the best fo r this purpose because of th eir stiffness. Lay this strip of substrate on top of th e leading edge of the textile and loa d the two together as described below.
NOTE: You can specify th e maximum permitted amount of ske w at the front panel: se lect the icon, then select Substrate handling options > Max skew setting . 5. Wait until the substrate e mer ges from the printer, as shown in the following graph ic.

3. Pull out the substrate fro m the front of the printe r. 4. Remove the empty spindle from the printer, pulling out the end on the right side of the printer first. Do not inse rt your fi ngers into th e sp indle sup ports during the removal process. 5.
2. If you want to lo ad the take-up reel n ow, select Load take-up reel now on the fro nt panel. If you want to load the take-up reel du ring printing, select L oad it during printing on the front pan el. 3. Make sure that the load ing table is in its upright positio n.
6. Remove the blue stop from the spindle. 7. Load the core onto the take-up reel spindle. 8. Replace the blue stop on the spindle. 9. Load the take-u p reel spindle into the prin ter by pushing firmly on both e nds of the spindle.
10. Press the OK button on th e front panel, and th en select a winding directio n. The printer advances the substrate. Make sure th at the substrate passes in front of the lo ading table, as shown. 11. Pull the substrate taut to the position sho wn in the following fi gure.
12. Press the OK button on the fro nt panel. The printer advances th e substrate. 13. Assemble a loop -shaping core by ma tching the shap e-coded and color-coded le ngths of plast ic tubing. The loo p-shaping core must be the same width as the su bstrate that yo u are using.
15. Carefully insert the loop-shapi ng core. NOTE: Make sure that you insert the loop-shapin g core. The take-up re el will not function correctly without it. The loop-shapin g core must ha ve end caps. Make sure that the end caps extend over the edges of the substrate.
NOTE: If you want to move the printer, first remove the take-up reel sensor and cable housing u nit from the foot of the printe r stand. Place the sensor and cable housin g unit on the printer stand crossbar and use the blue plastic screw to affix the housing unit to the leg of the stand, as show n, while the printer is being moved.
4. Remove the loop-shaping core. 5. Use the win ding button on the take-u p reel moto r to wind t he excess substra te around th e take-up reel spindle. 6. Press the OK button on the fron t panel. 7. Use the winding button on the take-up reel motor to wind the remainder of the sub strate around the take-up reel spindle.
9. Unlock the take-up reel spindle by pushing the spindle leve r to its uppermost position. 10. Remove the roll from the printer, pulling out the end on the right side of th e printer first. Do not insert your fingers into the spindl e supports during the removal p rocess.
● Allow all substrates to adapt to room conditions out of the packaging for 2 4 hours before printing. ● Handle film and glossy substrates by the edges or wear cotton gloves. Skin oils can be transferred to the substrate, leaving fingerprint marks.
9. Check the qu antity of ink and correc t it if there is too much; see Check the ink quantity on page 37 . The print may not be completely dry at this stage; this is normal an d not a problem. 10. After a little time, the print should be completely dry.

Setting Description If too low If t oo high Input tension Te nsion is applied to the substrate from the input spindle. It needs to be constant over the full width of the substrate, thus substrate load is a critical operation. The substrate skews and may become increasin gly wrinkled in the printing zone.
Setting Description If too low If too high Cool-down curing temperature offset The saf e temper ature at w hich the substrate can be under the curing module without being damaged. At the end of a job, the substrate is not stopped until this temperature is reached.
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.
● 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.
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.
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. Each ca rtridge has a capacity of 775 ml. Ink cartridges require no maintenanc e or cleaning.
Although it is possible to use re filled or non-HP ink ca rtridges, either choi ce has several serious disadvantages: ● There is some risk of damaging the printer. In this case the printer warranty will not be valid for any printer repairs tha t are related to the cartri dge , nor fo r any problems due to ink contami nation.
CAUTION: Avo id touching pins, leads, and ci rcuitry when handling in k cartridges because these elements are se nsitive to electrostatic dischar ge . Such devices are called ESD-sensitive devices.
