7. Do not depress the on/off switch. It should
remain on for the entire working day. As long as the
on/off switch is in the on position, several functions will
occur throughout the day.
a. Approximately every 4 minutes, the
oscillating pumps will cycle for several seconds. This
action will maintain a uniform solution strength.
b. The solution heater will maintain a proper
c. The solution agitators will intermittently
cycle, keeping the solutions well mixed.
d. The roller transports will intermittently turn,
allowing the solutions to wet the rollers. This will
prevent dried solution deposits from forming.
e. At the end of the working day, depress the
on/off switch to the off position.
8. Some models may require that you turn the
water inlet valve on the plumbing line to the off
Procedures For Processing Film
If you are processing a large quantity of X-ray
film, you must avoid any mixup. To do this, after you
insert one patients X-ray films, wait 15 seconds before
inserting the next patients films. After inserting the
X-ray films of each patient, set the X-ray mount,
envelope, or identification label aside, making sure to

keep them in the order in which they were processed.
This will help you match the processed radiographs to
the patients unit, envelope, or identification label
when the film exits the processor.
To process X-ray films, you should follow these
1. The recommended complete processing time is
5 minutes at normal speed. If your processor has an
endo speed button, this can process X-rays in 2 minutes.
Endo speed is used when the dentist wants to process the
film quickly. The developer temperature should be at
82°F (28°C) and the water temperature 50°F to 90°F.
2. Depress the run/standby switch to the run
position to begin automatic processing.
3. Insert the X-ray film. Unwrap the film and insert
it into the film receiving slot. (Remember to open the
film under safelight conditions). The automatic
processors can have up to six tracks to accept intraoral
films. To prevent overlapping, feed the film lengthwise
into every other track (e.g., insert first three films into
tracks 1, 3, and 5; insert the second three films into
tracks 2, 4, and 6). Feed large films lengthwise one at a
time, allowing at least 15 seconds between films. Allow
15 seconds to expire after the last film disappears before
inserting another film or turning on the lights or opening
the darkroom door. Once the films have been inserted,
the total processing time will take 5 minutes unless on
the endo cycle.
