Direct answer: A service log records the actual machine configuration, checks, consumables, symptoms and repairs over time. It helps operators and technicians see changes, but it does not replace the manufacturer’s maintenance schedule or a qualified diagnosis.
Engineering Principles and Components
| Topic | Function | Practical check |
|---|---|---|
| Machine details | Record model, serial, installed head and relevant software. | Avoid recording passwords or credentials. |
| Routine checks | Record date and the approved check result. | Attach or reference test patterns where practical. |
| Consumables | Track compatible inks, filters and service items. | Record changes and supplier details. |
| Faults and repairs | Record symptoms, error codes, work done and technician. | Keep invoices and warranty documentation securely. |
Practical Shop Checklist
- Use one log per machine and assign responsibility for completing it.
- Record approved checks without exposing confidential client artwork.
- Note unresolved faults and escalation contacts.
- Review recurring issues with qualified service before buying replacement parts.

Frequently Asked Questions
What should a service log contain?
Model, serial, dated checks, consumable changes, faults, authorised repairs and service contacts.
Should I store passwords in the log?
No. Use a separate approved credential manager rather than an operational log.
Does a log replace an AMC?
No. It supports communication and history but does not itself provide service coverage.
How often should I fill it in?
Record checks and maintenance when they occur, according to the machine’s schedule.
Should I keep nozzle test patterns?
Yes, where practical, dated and associated with the machine configuration.
How does it help diagnose faults?
It shows when symptoms or configuration changes occurred and helps an engineer compare observations.
What should I do with customer artwork in service records?
Avoid storing unnecessary client files; protect any required data under the agreed handling policy.
