What spare parts are worth buying with the camera
With the camera, buy a lamp that may go out of production, a wear-prone encoder, and a spare lens cap. A spare main unit can wait. A dead lamp stops inspection the same day.
The spare parts worth buying with the camera are a lamp that will go out of production, a wear-prone encoder, and a spare lens cap. A spare main unit can be talked about later. If the lamp dies, inspection stops the same day. If the encoder dies, register and the metre count both report wrong.
Why it is judged this way
Ordering the lamp after it dies often takes longer than the loss from the stop. Ask the lamp model and whether it can still be bought. The encoder must be the same resolution. Do not swap in one with a different pulse count on the spot. Write these into the unpacking list. Do not receive only the camera body.
What to compare
| What you see | What to call it | What not to do |
|---|---|---|
| The lamp has a model and there is one spare | It can get through one failure | Buy only the camera |
| The encoder pulse count is different | It cannot be a spare | Fit it and see |
| There is no lens cap | Wiping is likely to scratch it | Make do with a shirt |
At job change or when a roll is opened
- The order lists the lamp and encoder models on their own lines.
- Check that the spare lamp swaps on directly.
- Count the parts when the box is opened. Do not add them afterwards.
