7.3
Before proceeding, take note of the following warning.
WARNING: If the printer must be moved with the ISA in the raised position, do not use the left-side cover or support arm
as a hand hold. The cover can easily detach from the printer and break, which allows the ISA to suddenly drop to the closed
position causing damage to the ISA or personal injury.
7.4
Raise the ISA.
7.5
Use the locking arm to secure the ISA in the raised position.

the chassis (stretch the belt to install the gear).
3. Install the pulley cover and screw.
IMPORTANT: The repair kit contains two sets of tools used to install
the mezzanines. Failure to use these tools results in incorrectly
positioned mezzanines that will not properly operate (and might be
damaged when the printer power is turned on).

tools. These tools lock the mezzanines in a specic position along
the drive belts.
12.2
Before proceeding, note that the right-side mezzanine tool has a
front side (callout 1) and a rear side (callout 2).
NOTE: When correctly installed, the front side (callout 1) of the tool
faces the interior of the nisher chassis (toward the mezzanine).
12.3
Before proceeding, check the replacement mezzanines to see if the
belt clamp (callout 1) and ground spring (callout 2) are pre-installed.
If these parts are installed, do the following:
1. Remove one screw , and then remove the belt clamp (callout 1).
2. Remove the ground spring (callout 2).
TIP: Use a small at-blade screwdriver to carefully pry on the back
side of the spring to release a press-t burr. Pull straight up on the
spring to remove it.

Position a mezzanine with the front most wheel (front mezzanine)
or rear most wheel (rear mezzanine) aligned with the posts on the
rail (callout 1; front mezzanine), and then push the tool down until
it snaps over the mezzanine wheel and onto the post (callout 2).
NOTE: When properly installed, the tools are secure (callout 3) and
rmly hold the mezzanines in place.

Before proceeding, take note of how the mezzanine belt clamps are
installed:
• Front mezzanine: The lower portion of the upper drive belt
passes over the clamp (callout 1).
• Rear mezzanine: The upper portion of the upper drive belt passes
under the clamp (callout 2).
