In-Line Process Controls
Automatic. Routine. Accurate.
Process Control “ProCon” is the in-line process by 
which CMYK patches are laid down on the IBT 
(Intermediate Belt Transfer) and read via internal 
sensors throughout a print run. The number of patches 
and frequency is optimized for speed and quality.
The end-user may be unaware of the automatic, routine 
density checks in a print run—You may see “Adjusting 
Image Quality” flashed on the top of the C60/C70 User 
Interface.
.
Automatic Sensor Adjustments: (TRC)
• 13%,30%,45%,60%,75%, 100% patches 
for CMY
• 15%,30%,50%, 100% patches for Black
Real Time Run Control Patches
• Startup/Power and after 4 hours of 
inactivity, Temperature and humidity 
change 
• When the fuser area is opened and 
closed, 
• When changing from Uncoated to Coated 
stock 
During Print Runs (no interruption) 
• Two color patches at a time (C and K, Y 
and M, colors in station 1 and 2) are 
developed in the inter-image area and 
read by the In and Out ADC Sensors to 
make slight changes on the fly: 
An 75% patch for Color (devbias)
An 50% patch for Black (devbias)
Process Controls are run automatically 
by the C60/C70—Before, During and 
After Printing
