Chapter 1 Product Overview Auto Nozzle Check System This printer is equipped with the automatic nozzle check function. The setting can be changed depending on how much deterioration in print quality (missing dots) caused by clogged nozzles can be allowed. The printer performs the nozzle check at the following timing. • When the printer is turned on • When the paper cover is closed after a paper jam • Just before running a regularly scheduled cleaning ( "Periodic Auto Cleaning" on page 34 ) If nozzle clogging (missing dots) is not resolved even after head cleaning, complementary printing can be performed using nozzles adjacent to the clogged nozzles.
By using these functions, you can prevent sharp decline in the print quality and barcode quality. • This function does not completely prevent nozzle clogging. The printer cannot perfectly detect missing dots and skewed ink drops on printouts. • To prevent misreading of characters that are partially missing due to nozzle clogging, it is recom- mended to use the printer with its default nozzle check settings. For information about the default settings, see [Maintenance] - [Nozzle check settings] in "Operation Panel Settings" on page 223 . • If extremely high reliability is required for printouts, it is recommended to use fonts whose height is 3-dots or more.
c IMPORTANT • If [Perform Head Cleaning when Clogged Nozzle Detected] is set to [On] or [On(Not During Print- ing)] and the number of detected clogging nozzles exceeds the set [Threshold of Clogged Noz- zles], head cleaning will be performed automatically. After head cleaning, the nozzle check is performed again, and if the check result still exceeds the threshold, head cleaning is run again. Ink is consumed for the head cleaning. • The head cleaning is performed on only those heads and inks with nozzle clogging detected, or on all heads, depending on the nozzle clogging condition. • A small amount of ink is consumed for the auto nozzle check system.
Nozzle Check Basic Settings The following are basic nozzle check settings. • Threshold of Clogged Nozzles • Perform Head Cleaning when Clogged Nozzle Detected Threshold of Clogged Nozzles (Criteria for Judging Nozzle Clogging) Specify the allowable number of clogged nozzles to be used for the self nozzle check system. If the number of clogged nozzles exceed the set number, the printer performs the operation set by [Perform Head Cleaning when Clogged Nozzle Detected]. If the number of clogged nozzles is less than the set number, you can select to use the complementary printing (Dot substitution) function. The factory default is “6”.
How to Set Set using the operation panel of the printer, or using PrinterSetting. See "Operation Panel Settings" on page 223 or "PrinterSetting (Windows)" on page 185 . 30
