175 Printing Operation5.1 Printhead Protection! Attention!Printhead damage caused by improper handling! Do not touch the underside of the printhead with the fingers or sharp objects. Ensure that the labels are clean. Print with the lowest possible printhead temperature.5.2 Synchronization of the Paper FeedAfter the label stock has been inserted, for peel-off mode a synchronization of the paper feed is required. That waythe first label, which is detected by the label sensor, will be transported to the print position and all labels in front willbe fed out of the print module. So the synchronization avoids, that blank labels are peeled-off together with the firstprinted label. This can cause useless first label. Press the feed key to start the synchronization. Remove the blank labels peeled-off during the synchronization.i Notice!Synchronization is not necessary if the printhead was not opened between different print jobs, even if theprint module was switched off.5.3 Printing! Attention!To start the print operation two steps are necessary : Send a print job via data interface or load a print job from a memory medium. Programming Manual, Configuration Manual Start a print cycle by sending external signals via I/O interface. Interface Description5.3.1 Peel-off ModeIn Peel-off mode, the labels are automatically peeled off the liner after printing and presented for removal.! Attention! Activate the peel-off mode in the software.This is done with the "P command" in the direct programming, Programming Manual.5.3.2 External RewindingThe printed labels are leaving the print module at the peel-off edge and may be wound up externally with the liner forlater use.5.3.3 Ribbon SavingIf there is no information to print during a longer label feed, the printhead will be lifted, and the transfer ribbon will bepaused from feeding. This will reduce the ribbon consumption. The minimum length for ribbon saving is defined in thefirmware and depends on the print speed.The ribbon saver can permanently be activated in the printer configuration ( Configuration Manual) or job-orientedby the software ( Programming Manual).
