Toner Cartridge and Photoconductor Units
The ST9612 MICR Print Cartridge is comprised of two components: the toner cartridge
and the photoconductor unit.
Toner cartridges are available in two models depending on the yield: a 1.5K page and a
3K page. The 1.5K model ships with new printers. The 3K model is the normal
replacement model. The projected life in terms of page count is based on a typical 5%
print coverage and continuous print mode. These projected values of 1,500 and 3,000
were certified using the ISO 19752 Yield Testing Methodology. The standard requires
continuous print mode. The projected life is reduced somewhat dependent on the actual
average print-job page count.
The photoconductor unit has a projected life in terms of page count of 20,000 to 30,000
dependent on average pages per print job. The 20,000 life is projected for 100% 1 page
print jobs. The 25,000 life is projected for an average print job being at or near 3 pages.
The photoconductor life for average print jobs being above 3 pages would exceed the
25,000 forecast.
The ST9612 MICR printer keeps record of the actual printing modes in terms of average
print job size and the actual average print coverage percentage. The printer internally
adjusts when either the toner cartridge or photoconductor unit needs to be replaced.
The following error messages pertain to the toner and photoconductor unit.
Toner Low
The printer will stop with the Toner Low / Replace PC light and the Continue button ON
steady. Press the Continue button and the printer will return to Ready and continue
printing. The Toner Low light will remain ON, steady. While in the toner low state, the
printer will stop again on power cycles and other operating situations such as jams or
paper out conditions. Simply press the button to continue printing. The Toner Low light
will remain ON until the cartridge is replaced or Toner Out is reached.
