The two substrate rolls are mounted on the rear dual-roll spindle and will be collected on the front dual-roll spindle. The substrate goes from the rear spindle over the main roller, over the platen, over the front roller and then to the front spindle.
הערה:You can load substrate with the printed face inwards or outwards on the spindle, in which case the spindle will turn in the opposite direction. The printer asks you for the winding direction if it cannot detect it automatically.
Before loading two rolls into the printer, you must have both rolls loaded on the rear dual-roll spindle and two empty cores loaded on the front dual-roll spindle. See Load rolls onto the spindle.
-
Tell the printer that you are going to begin loading for dual-roll printing.
-
Remove the substrate edge holders in the print platen, or move them aside, so that they do not get in the way while loading the substrate.
שים לב:
Loading the substrate on top of the edge holders could severely damage the printheads and carriage. -
Lift the substrate pressure handles at the rear of the printer.
-
If you need to raise the carriage beam, go to the front panel and select the Substrate menu
, then Substrate management, and press OK. Select Carriage beam position > Move to highest position. This process takes about 2 minutes to complete.
The printer raises the carriage beam, making it easy to insert the substrate. This process takes about 2 minutes to complete. During this period, you can load the input and output rolls.הערה:
While the carriage beam is rising, you can stop it by pressing the Cancel key. -
You may find it helpful to lock the differentials on the input and output spindles while loading.
-
Bring the new rolls on their spindle to the rear of the printer, with the geared end of the spindle on the left.
-
If the two rolls are of unequal lengths, the longer roll should be on the right as seen from the front of the printer; on the left as seen from the rear.
הערה:
When the shorter roll comes to an end, you should lock the differential hub if you intend to continue printing on the longer roll. -
Rest the ends of the spindle on the platforms provided at the rear of the printer; plastic pads are provided to absorb the impacts.
-
Open the latches at both ends of the spindle (if they were closed) and push the roll on its spindle into the printer.
-
Close the latches to secure the spindle in place.
הערה:
If you cannot close the gear side latch, try sliding the spindle towards the side plate to make sure the end flange is not sitting on the bearings.
-
In the same way, load the spindle with the empty cores into the front of the printer. In this case, the geared end of the spindle should be on the right.
-
Check that the printer has finished raising the carriage beam.
-
Pass the leading edges of both rolls through the printer to the output spindle.
הערה:
Two people are recommended for this operation (one per roll).
-
Install the two central edge holders, which can be done most easily at this stage.
-
Once in front of the printer, if you find that you haven't unrolled enough substrate, select Start main roller motion from the front panel's Substrate menu to unroll some more. The substrate unrolls only when you pull it.
-
Before taping the leading edges of the two substrate rolls to the empty cores on the output spindle, check by measurement that they are in the same positions on the output spindle as on the input spindle.
-
Tape the leading edges of both rolls to the empty cores on the output spindle.
-
Ensure that the four edge holders are correctly positioned, leaving the substrate free to move.
-
Unlock the differentials on the input and output spindles.
-
Go to the front panel and select the Substrate menu, then Substrate management, and press OK. Select Carriage beam position > Move to printing (normal) to lower the carriage beam into its normal position, close to the substrate. This process takes about 2 minutes to complete.
הערה:
The Move to printing (custom) position allows you to set the printhead-to-substrate distance for thick substrates or substrates that may wrinkle in the print zone, to avoid ink smearing. Be aware that raising the printhead from the substrate may give poorer print quality.אזהרה:
Do not insert your hands or anything else into the printer while the carriage beam is descending. -
Tell the printer to check the loaded substrate. The printer rotates the rolls to check their diameters, and it also checks the width of the roll, the winding direction, the vacuum and the substrate advance calibration (this takes 3–4 min).
הערה:
Some substrates (such as transparent substrates) cannot be measured by the printer in this way. In such cases, you will be asked to enter the required information manually. Use the scale on the curing module to see the value for the right-hand edge that must be entered manually. -
In the HP Internal Print Server, choose from the list of substrate types the type that you have loaded.
The contents of the Loaded Substrate window are determined automatically when the substrate is loaded and checked. However, if the printer is unable to detect the edges of the substrate (for instance, in the case of a transparent substrate), you will have to measure the distance of the left edge from the printer's side plate, and complete the Left Edge and Width fields yourself.An alert regarding substrate advance tracking may appear at this point. For more information, see your printer's documentation.
The printer is now ready to print.
