18 185 Printing Operation! Attention!Printhead damage caused by improper handling! Do not touch the bottom side of the printhead with fingers or sharp objects. Ensure that the labels are clean. Ensure that the label surfaces are smooth. Rough labels act like emery paper and reduce the service lifeof the printhead. Print with the lowest possible printhead temperature.The printer is ready for operation when all connections have been made and labels and, if applicable, the transferribbon have been loaded.5.1 Synchronization of the Paper FeedAfter the label stock has been inserted, for peel-off or cutting mode a synchronization of the paper feed is required.That way the first label, which is detected by the label sensor, will be transported to the print position and all labels infront will be fed out of the printer. So the synchronization avoids, that blank labels are peeled-off together with the firstprinted label or that the first cut label would be too long. Both effects can cause a useless first labels. Select to start the synchronization. Remove the blank labels peeled- or cut-off during the synchronization.5.2 Tear-off ModeAfter printing, the label strip is removed by hand. The label printer is equipped with a tear edge for this purpose.Loading labels 4.1 on page 11 oder 4.2 on page 13.5.3 Peel-off Mode MACH 4.3S/200P, MACH 4.3S/300P, MACH 4S/300P and MACH S4/600P onlyIn Peel-off mode, the labels are automatically peeled off the liner after printing and presented for removal.The label in the peel position will be detected by an optical sensor. After the label has been removed the next labelwill be printed and fed to the peel position.Loading labels 4.3 on page 14.! Attention!Peel-off mode must be activated in the software.This is done with the "P command" in the direct programming Programming Manual.5.4 Cutting Mode MACH 4.3S/200C, MACH 4.3S/300C, MACH 4S/300C and MACH S4/600C onlyThe labels or continuous material is cut-off automatically. The relevant cutting position is preferably set in thesoftware.Loading labels 4.1 on page 11 oder 4.2 on page 13.! Attention!Cutting mode must be activated in the software.This is done with the "C command" in the direct programming, Programming Manual.
