Its enough that one of those junctions or curves have a partial blockage to lower the pressure on the entire system.
It might also be be that the pump motor has reached the end if its service life, its a very easy replacement. If you see lower pressure, try tapping the motor on the rear of the machine and try flexing and squeezing/pinching the visible or accessible hoses with your fingers and see if they spit out any gunk through the spout at the upper trough. The mesh wire filter should catch most of it before its sucked back to re circulate.
Processor clean can help loosen up the gunk as well.
Let me know if you still need any help.
Bearings can certainly seize or be gummed with lubricant (my CPP2 pump has this issue), pumps themselves definitely wear out at points of contact and/or flex. But not motors. Electric motors are forever unless abused ;)
If your electric motor has stopped, clean & re-lube it, maybe replace a bearing. If it's part of a pump, the actual pumping bit should be your prime suspect.
That might be all true - but in this case the pump and motor are a single cased unit.
There is no way to gain access to the pump, or motor without breaking the housing...
Sometimes that unit needs to be replaced.
Fair enough then. Totally different to a CPP pump.
I am using the CPP3 now for film processing, I cannot comment on making prints with a Jobo a I never have done this but know many that do very well.
I can comment on the CCP3 however as we have just put one into production here.
The CPP3 has a great countdown program for putting chem in and out which I found at first a bit daunting, but once you get use to it quite easy to master. It is easy to program different process times and setups, just takes a bit of time as well to figure the logic of whoever wrote the little manual.
The unit is very robust in circulation so once turned on the temp can be kept active all day long. I also like the feature of the small filler bottles warming up right next to the main run bottles , with a few tanks one could just print all day long with some pretty good production.
Those people who wash off processor like us can really speed up the usage of one of these machines.
I think a priority for print processing would be a very good drying cabinet that can keep up to the printer. Colour correction has to be done dry so being able to get there fast would be IMO important.
When I first started colour printing, fall of 1974 I was assigned a small room to share with one other, It was equipped with a chromega enlarger and a small wet sink that housed a K16 colour processor... any one remember this processor.... it was super cool to say the least for a young student to learn photography with their own kit to make images. Back in those days we had 24/7hours access to the lab and studios ,and I basically lived there for three years.....
Now I live here with enlargers and processors , not much has changed other than the magic of Photo Shop has opened some big doors...:munch:
So to the OP go for it , get a chromiga , get a Jobo and buy cut sheet and have the time of your life.
Well..., yesterday I fired up the Jobo and ran a trial process, however once the machine had dumped the third solution the dreaded 'air diffuser faulty' message came up again; attempts to alter tension in the sprung arm that dumps process solutions did not result in a lack of error message unfortunately, whereas previously (2010 as it turns out) I had managed to work the mechanism free and continued processing. I may have another go this afternoon but I'm reluctant to start spending money on replacement parts when something else might stop working soon...
Thats sad news. See if you can jimmy out and keep us posted. It might be time to trade up to a new machine...
