Media tracking
Tracking is the process that controls media motion over the platen
and assures accurate lines. If the paper slips under the pinchwheels
or is out of alignment, printing quality will degrade. To resolve
tracking dif fi culties try the following suggestions:
 Install paper correctly. See the Operation chapter in the User
Guide for more details .

Make sure the paper path and dancer bars are set correctly (as
shown in Figure 22 (and in the User Guide .)
 Inspect the paper for wrinkles or folds. Never use paper that is
folded, wrinkled, or torn in any way. It may cause paper jams.

Make sure the pinchwheels are spaced across the paper as out-
lined in the User Guide .
 The pinchwheels should never be positioned over bearings on
the drive shaft as paper tearing and bunching will occur. Verify
that the pinchwheels are positioned over treads (e.g. under the
white markers af fi xed to the traverse.)

Check to make sure that the printer is level. See the Quick Start
Guide for more information .

The paper may slip when debris accumulates on the drive shaft.
Inspect and clean the drive shaft. Refer to the Routine Mainte-
nance chapter in the User Guide for more information.

Contact an Ioline distributor or Ioline Customer Service if you
are unable to resolve the problem or if the printer is damaged.
Print quality problems
Line quality
In most cases, poor line quality is caused by one of several things:

The ink cartridge is empty, dirty, damaged or dried up.

The Motion Factor or Carriage Calibration needs adjustment.

The platen is not level
If line quality is uneven, try the following:
1. Press
Start/Stop then the Clean keys
on the keypad to automatically clean
the cartridges.
2. Inspect the ink level window on
cartridge. If it is black, then the
cartridge is empty. Replace it with a
new one.
3. Remove the cartridge(s) and manu-
ally clean the print head with a (de-
ionized) water-moistened, lint-free
cloth. (See Cartridge Maintenance and
Handling in the User Guide .)
