Small mistake - when the printer is left idle overnight with ink temperature on, after certain time heating is switched off automatically, so inks are cooling, but it's possible to set the time when the heating will be switched on again (i.e. in the morning, before the beginning of the shift).

First of all - what is the vacuum pressure value (given on the console screen on the ink management tab)? Are there any errors listed (or simply message 'vacuum system problem')?

Gareth, so you need an engineer with the SDS key to check the ink heating system.

On April 28th there was an error 'Ink temperature far below the setpoint'. Almost immediately errors 'Ink heater not heating' appeared with the decreasing value of the temperature. Now the temperature is around 19-20 Celsius degrees (I suppose it's the room temperature). It's still possible...

It may be related to a few problems: - the thermistor in any of the heads may be switched off (it happens sometimes) - lack of electric contact in any of the head - broken one of the two coolant pumps (one supplies coolant to the carriage, the second one circulates the coolant) - broken coolant...

Jetrix has three distributors in the USA - Ohio, New Jersey and Idaho. Try to ask them maybe?

It depends on the machine, as you wrote, but for example flatbeds from OCE/Fuji may stay powered for a long time without switching off. Special procedures are required when the machine should be switched off for a long time (more than two weeks).

First of all - what was done with the heads before the installation? How the holder was positioned? That may affect quality. Second - shim installation is obligatory, even if the printer has no shims installed. After shimming (even one head) "carriage angular" calibration shouldn't be done...

It's possible that it's only the slanted flat cable between the head and the board. Or maybe there's lack of contact on the cable. I've seen such high temperatures when was only a small problem with the flat cable - it's worth to try it (maybe the technician check it already?). It's not possible...

As I know, it's possible to switch off the whole head (one line of the nozzles) - each one is treated as a separate head. It's possible to set the head voltage to 0 (remember to write the proper value of the voltage somewhere to set it back when required) - it won't print anything. But I'm not...

The procedure says, that you have to switch off the lamps, table vacuum and ink heating. That's all for the weekend (and of course overnight).

Ask your local Fujifilm distributor about the flatbed with KV inks. They are designed for vacuum forming (elongation up to 1000%, perfect 90 degrees angle).

The ATX power supply is powered from the AC breakout board located in the electric box (near the main switch). There is a separate fuse for this line, it's F4 (4 amps). Maybe it's only the fuse (but question would be, why it's broken...). Of course, it may be also related with the breakout board...

Check, if the LED diodes on the computer motherboard and mainboard are on when you switch the printer on. If not, check the power supplies.

If you have the degas modules installed in your printer, check all connections and the modules itself - there may be a leak somewhere or the module is damaged internally and air may not be removed from the ink.

First of all - check the head type in your carriage. Each head should have a label with the model. CA4 is an old model - it's a single head. CE2 head is a combo - two CA4 glued together. Different versions of CE2 have different ink/vacuum inlets, so you need to buy the same you have inside your...

I see some words are too difficult for you, like 'irony' or 'sarcasm'. And of course 'forum rules'.

For sure this client waits since 2011 for you to have the printer repaired... First thing when you try to repair anything - THINK.

Toshibatec heads just look similar, but they have differences - it's not always possible to swap them. And of course, if you reinstall the holder from the old head, don't be surprised when you won't have the perfect calibration.

The main part replaced after a year in this machine is an ink tube in the pump. Maybe the air filter in the box, where the ink pumps are located, but it depends how dirty it is (remember that if you replace this filter, you need to check/calibrate the pressures in the ink system, especially...
