CW — Print Quality Problems

Chapter3 Handling Print Quality Problems 317 Status Cause Solution Horizontal White Banding The nozzles are clogging. Print the nozzle check patterns to check the nozzles for clogging. ("Test Print" on page 83) If the nozzles are clogging, run a print head cleaning. ("Cleaning the Print Head" on page 306) White or Black Banding The paper is not loaded correctly. Reload the paper. ("Loading Paper" on page 67) The paper being used and the Media Coating Type setting differ. Check the paper being used and the Media Coating Type setting of the printer driver.

("Printer Driver for Windows" on page 85) White banding or black banding can occur if the paper feeding setting is not appropriate for the paper used. Adjust the paper feed settings. The adjustment is available in [Print Head Alignment] of PrinterSetting. ("Print Head Alignment" on page 209) Unintended Top and Bottom Margins are Generated If die-cut label (without black marks) thinner than required thickness is used, the printer may not be able to correctly detect the labels and cause unintended top and bottom margins on each label.

(The “top and bottom” used here means the beginning and end of labels in the paper feed direction.) Carry out [Print start position adjustment (Vertical direction)] of PrinterSetting. Enter a minus correction value to reduce the top margin, and enter a plus correction value to reduce the bottom margin. ("Position adjustment" on page 196) Printed Characters Look Blurred The outside shutters on the platen, which are not needed to be opened for the paper, are open. Air flow from the outside shutters adversely affect the printing operation and may cause blurred print. Set the shutters on the platen according to the instructions on the label attached to the printer.

("Adjusting the Shutters" on page 79) Blurred print may occur when the printer settings are not appropriate for the thickness of the paper. Carry out [Bi-directional Printing Adjustment] of PrinterSetting. ("Print Head Alignment" on page 209) Printed Colors Are Wrong If the printer is moved after initial charging, the specified colors may not be output (colors may be mixed) due to vibrations and impacts. Run a head cleaning and check that colors are no longer mixed. ("Cleaning the Print Head" on page 306)
