SECTION in - MECHANICAL ADJUSTMENTS
A. IMPORTANT CONSIDERATIONS
The rugged mechanics built into Delta Series
cartridge machines are designed to provide ex 
tremely reliable and long-term operation with a
minimum of simplified adjustments. The sequence in
which mechanical adjustments are completed,
however, is important due to the fact that many of
these adjustments are interrelated. Therefore, if a
complete check of all mechanical adjustments is
required, start at the beginning of this section and
follow the proper sequence.
GAUGE, PRESSURE ROLLER PRESSURE
(830-0042-011)
Figure 3-1
Alignment gauges to which references are made
are available from ITC.
The pressure roller pressure gauge, 830-0042-
011 has been designed exclusively for use in the ITC
Delta Series. When utilized for either checking or
adjusting pressure roller pressure, a clear under 
standing of its purpose will be most helpful in mak 
ing an accurate and speedy set-up.
The three primary width dimensions are shown.
Dimensions "A" and "B" are used to measure the
range of pressure roller pressure. Dimension "A"
measures maximum roller pressure. Dimension "B"
is used to show when pressure roller pressure is too
low. The pressure of the pressure roller is properly
adjusted when dimension "A" slides between the
capstan shaft and pressure roller shaft and dimen 
sion ” B" does not.
Dimension "C" is a low-tolerance dimension,
and should never be used to measure any mechan 
ical parameter in the Delta Series. Its prime function
is as a handle and may be held at this point or at
any place along its length.
B. PRESSURE ROLLER SHAFT/CAPSTAN SHAFT
(MOTOR) POSITION
The following adjustments are necessary if a
motor or solenoid has been removed. The adjust 
ment should be checked any time a new pressure
roller is installed.
NOTE: The pressure roller capstan shaft locator
gauge (ITC Part #830-0043-001) and the pressure
roller pressure gauge (ITC Part #830-0042-011) are
required for the following procedure.
Procedure for Delta I and Units
1. Remove the pressure roller and place the spe 
cial locator gauge (830-0043-011) over the pres 
sure roller shaft as illustrated in Figure 3-2. Man 
ually move the gauge up to (against) the cap 
stan shaft. Check to see that the gauge surface
lies flat against the capstan shaft. If not, loosen
the motor mounting screws, and gently move
the motor until the gauge surface and the motor
shaft are "flat" against each other.
