Strip Chart Recorder: Paper Error Conditions
Paper Error Conditions
A 170 Series Monitor indicates when the recorder is completely out of paper and
when the strip chart paper is incorrectly loaded.
Paper-Out Condition
When the recorder runs out of paper, the monitor automatically ejects the paper and
then turns off the recorder. The Record indicator flashes until you load paper.
Paper-Load–Error Condition
The instructions for loading paper into a 120 or 170 Series Monitor are different
than the instructions for loading paper into other Corometrics monitors with which
you may be familiar.
To protect against paper jams, the 170 Series recorder contains a paper-loading
sensor which detects if the paper is incorrectly loaded. When the recorder detects a
paper-load–error condition:
the recorder does not print;
the Record indicator flashes on and off every second; and
three short beeps (with a low tone) sound every three seconds at a fixed volume
until the condition is resolved (The volume cannot be adjusted.)
The most likely cause of a paper-load–error condition is that you loaded the paper
with the black squares facing up. The correct method—for 120 and 170 Series
Monitors— is to load the paper with the black squares down. To correct the
problem:
1. Follow the instructions for “Removing Unused Paper from the Recorder” next
on this page.
2. Follow the instructions for “Loading Strip Chart Paper” on page 4-2.
