Medical Imagers and Film Printers — Level 2: Fault-Finding
From the jam, artefact or DICOM error to the failed assembly: transport, thermal head, laser, processor, boards, network
Part of the program: Medical Imager and Film Printer Engineer — program (7 h) →
Level 1 taught you to clean, load, calibrate and hand back a film printer. Level 2 starts when the fault survives all of that. This course teaches the engineer to read the error history and counters for the first cause, to split a fault between film, transport, image writing, processing, electronics and the sending host with one cheap test at a time, and to follow it to the assembly that has really failed: pick-up, rollers and sensors, thermal head, laser and polygon, heated drum, densitometer, power supply, controller and storage, network and DICOM settings. It ends with the return to service: the measurements, test prints, constancy checks and records that prove the imager is fit to print again.
The code said hard disk. The settings had been scrambled by a power cut.
- Heads, lasers and controller boards are ordered because the code named their subsystem, while the real cause is an old film box, a glazed roller, a drum that runs a degree off or a configuration lost in a power cut.
- Jams and lines come back a week after the visit because the engineer cleared the sheet and printed one test film, without finding which sensor, spring, motor or deposit actually stopped it.
- After a board, disk or software job the imager prints again, but with another unit's settings, the wrong firmware set or no calibration check, and the next engineer inherits faults with no baseline and no backup.

Curriculum
Collect the error history, notifications and counters, use an internal test print and a few density readings to place an imager fault in film, transport, image writing, processing, electronics or the sending host, and know what you may and may not change.free
22 min02Film supply and transport at Level 2: pick-up, sensors, rollers and recurring jams
Diagnose recurring jams and pick-up failures to the sensor, cup, pump, spring, roller, motor or guide, using sensor states, swap tests, a jam map and the timing logic of the film path.22 min03Direct thermal printing: head, platen, pressure, cleaning and head replacement
Read lines and density faults on direct thermal prints back to the element, driver, debris, platen, pressure or drive, clean and inspect a head safely, understand resistance checks and head data in principle, and know what a head replacement and its calibration involve.22 min04Laser dry imagers: laser power, polygon, heat development drum and density drift
Separate writing faults from development faults on a laser dry imager, read laser power, polygon and processor errors for their real cause, check the drum temperature with a calibrated probe by procedure, and trace density drift to film, processor, optics or calibration.23 min05Image quality and calibration: densitometry, step wedges, LUTs, uniformity and artefacts
Measure density properly, read a calibration wedge as a characteristic curve, separate the imager's film calibration from the sender's LUT, check uniformity, and trace artefacts to film, processor, optics, head or configuration.23 min06Electronics and power: supplies, fans, interlocks, controllers, firmware and backups
Diagnose a dead, rebooting or erratic imager to the supply, fan, interlock chain, controller, storage or firmware set, keep a consistent firmware set and a configuration backup, and know which repairs belong to the workshop or the authorised service.23 min07DICOM print and networks at Level 2: associations, print attributes, queues and network tracing
Split a print failure layer by layer from the cable to the film, read association rejections and attribute errors, fix film size, layout and density mismatches at the right end, manage queues safely, and trace the network with simple tools and hospital IT.22 min08Complex cases and return to service: chained faults, consumables, QC, constancy tests and records
Untangle chained and double faults, deal with film and consumable problems within your authority, choose the QC checks that prove a given repair, run constancy tests against a baseline, and release or restrict the imager with a complete record.23 min—Exam

The certificate
Pass the exam and get a certificate of course completion with your name, hours and score. Every certificate has a unique number and a public verification page, so an employer or a customer can check it in one click. It confirms completion of the course; it is not an educational document (diploma) and not a manufacturer authorisation.

FAQ
Is this manufacturer training?
No. It is independent, vendor-neutral training. It does not replace the manufacturer's service procedures, does not grant authorisation or access to service software, passwords or licences, and every repair must still be followed by the adjustments, calibrations and checks the manufacturer and local rules require.
Do I need Level 1 first?
Medical Imagers and Film Printers — Level 1 is the prerequisite: laser, heat, mains and moving-part safety, film handling, jam clearing, the basics of density calibration, DICOM print settings and PM are assumed here and not repeated. The course DICOM, PACS and Networks for Service Engineers is recommended before lesson 7, and Electronics and Power Supplies — Repair Fundamentals before lesson 6.
Does it teach board-level repair?
It teaches fault-finding to the assembly and the replaceable module. Some field cases end in a power supply or board repair; that is workshop work and is covered in Electronics and Power Supplies — Repair Fundamentals.
Will it show me how to change the film region, activate options or reset counters without doing the work?
No. Region and licence settings, option activation, service passwords and anything that defeats an interlock or a maintenance reminder belong to the manufacturer and its authorised service, and are not taught here.
What does the certificate say?
Your name, the course, the hours, the date and your exam score, with a unique number and a public verification page.
Can my company buy seats for a team?
Yes: five seats and a progress overview for the manager.
