Page 163: Head Cleaning
Chapter 7 Maintenance Head Cleaning Head cleaning is a function for cleaning the surface of the print head, in order to maintain the print quality. Perform head cleaning if the printout is becoming faint or if there are gaps. The auto nozzle check function is installed to the printer, and the head is automatically cleaned in the normal operation.
Page 164: Manual Head Cleaning During Printing
Manual Head Cleaning during printing Normally faint and printing during printing or when it is printed in different colors, you can print the manual head cleaning while paper feed button is pressed. This feature is factory set to invalid. Please enable printer driver.
Page 165: Nozzle Check
Chapter 7 Maintenance Nozzle Check If the nozzle of the print head becomes clogged, the printout may be faint or a different color than usual even when there is ink. This product has an automatic nozzle check function, and normally, print head cleaning is automatically performed.
Page 166: Gap Adjustment
Gap Adjustment This is for adjusting misalignment in vertical lines and barcodes, and misalignment in paper feeding. Since gap adjustment is performed when the product is shipped from the factory, typically, the customer does not need to perform the adjustment. If the print position when the print head moves from right to left is misaligned with the print position when the print head moves from left to right, vertical lines may become misaligned or the print result may become blurry.
