Chapter1 Product Overview
Nozzle Verification Technology
The “Nozzle Verification Technology” allows the printer to detect clogging of the print nozzles by self-check.
Depending on required print quality, you can enable or disable the “Nozzle Verification Technology” function,
set how often to run the self-check, threshold for the check, and whether to run a cleaning after the check. In
addition to that, if nozzle clogging is not cleared by the cleaning, the printer carries out supplemental printing
using nozzles adjacent to the clogged nozzles.
By using this function, you can prevent sharp decline in the print quality and barcode quality.
Nozzle Verification Technology Settings
If the “Nozzle Verification Technology” function is enabled, self nozzle check is run at the time of the following
cases.
• When the number of printouts has reached the number specified as the interval of the self-check.
• When the printer is turned on
• When the front cover or the paper cover is closed after a paper jam
• Just before running a regularly scheduled cleaning
If the result of self nozzle check exceeds the specified threshold, a head cleaning is run automatically to clear the
nozzle clogging. After the cleaning, the self nozzle check is run again. If the result of the check still exceeds the
threshold, auto cleaning is also run again.
Enabling/Disabling the Nozzle Verification Technology
You can enable or disable the Nozzle Verification Technology function.
The factory default is “Enable”.
How to Set
Set using the operation panel of the printer, or using PrinterSetting.
See
"Operation Panel Settings" on page 145 or "PrinterSetting" on page 113.
CAUTION
This function cannot provide 100% accuracy guarantee for preventing drop in print quality due to
nozzle clogging. The printer cannot perfectly detect missing dots and skewed ink drops on
printouts.
• The cleaning cleans the entire print head. It does not clean the print head partially for cleaning
only the clogged nozzles.
• A small amount of ink is consumed for this Nozzle Verification Technology function.
• The print head cleaning is run automatically after the the self nozzle check when set to do so. Ink
is consumed for the head cleaning.
