Pen assessment and servicing
The Edgeline MFP pens need periodic assessment and servicing in order to maintain optimal image
quality. An assessment is made at different intervals to determine if pen servicing is necessary. The
intervals are at the beginning of a job, during a long job, at the end of a job, and at a daily scheduled
time. When an assessment of pen health occurs, every nozzle of every pen is tested. If the results show
a pattern of nozzle outs that may result in a print quality defect, pen servicing is invoked and the control
panel will display the message "Calibrating".
Servicing at the beginning of a job
If a unit is idle and a print job is sent, the MFP wakes up and performs pen servicing to get the pens
ready for printing. If the MFP has been idle for more than 8 hours prior to this job, pen servicing and
the "Calibrating" message is displayed for 3 seconds before printing begins. If the idle time has been
more than 7 days, extensive pen servicing is performed and the "Calibrating" message is displayed for
at least 20 seconds before printing begins.
Servicing in the middle of a long print job
If the MFP is idle and a print job is sent, the MFP wakes up and performs pen servicing to get the pens
ready for printing. If the MFP has been idle for more than 8 hours prior to this job, pen servicing and
the "Calibrating" message will be displayed for 3 seconds before printing begins. If the idle time has
been more than 7 days, extensive pen servicing will be performed that will result in the "Calibrating"
message displayed on the LCD screen for at least 20 seconds before printing begins.
Servicing at the end of a job
When the MFP is done printing, occasionally it will service the pens before it stores them for the next
job. When this occurs, the MFP will display "Calibrating" on the LCD screen. This message can stay on
the screen for 3 to 26 seconds depending on the types of pen servicing performed. On the average,
about every 180 pages of cumulative printing will result in pen servicing. An average user (19K pages
a month) will experience this pen servicing about twice a day, with the "Calibrating" message on the
LCD screen usually lasting for 3 seconds but can last up to 26 seconds. Since this pen servicing happens
only when a job is completed, it should not cause any printing delay unless the next job is sent right
after the pen servicing has begun.
