What to check first
Step-by-step checks
- 1
Safe first step
Keep printing only if the printer is otherwise stable and you understand the warning is still active.
Start with the official recovery step before moving on to parts or deeper servicing.
- 2
Escalate
Plan Canon support or replacement before the absorber reaches the full stop condition.
- 3
Escalate
Avoid unnecessary cleaning cycles because they shorten the remaining service life.
Background
What this message usually means
Canon uses support code 1702 when the TR4500 series estimates that the ink absorber is almost full. This is a warning-stage service-life condition rather than a low-ink alert, so printing can often continue temporarily but support planning is wise.
Diagnosis
Likely causes
The internal ink absorber has reached a warning threshold.
Cleaning cycles and purge routines filled the waste-ink area over time.
The printer's service counter is nearing its stop point.
Service
When service or replacement is more likely
- -This is a service-life warning, not a normal ink cartridge reminder.
