Guys, sc290 on a 3500, I know its a shutter motor or closed sensor issue, both a pain in the backside to get to (according to the manual). Its a secondary/back-up machine at a customer and the investment in the time nessesary is not possible. On some of the other models there is sp2914-007 where I think you can disable the shutter motor and remove the shutter and the problem goes away (can someone confirm this is so ?), however there is no sp2914-007 on the mpc3500/4500 to disable the motor. Is there any way this can be done ? I was thinking , if removing the lazer to get to the sensors and motor, can maybe the 'closed' sensor be manually bypassed ?, and of course the shutter would have to be removed. Would this work, and has anyone tried it ?

Re: mpc3500 sc290
Just remove the shutter, or make sure the firmware is up to date, there was an engine firmware for laser shutter codes. -
Re: mpc3500 sc290
Removing the shutter does not remove sc290 which is the sensor/motor issue.Comment

Re: mpc3500 sc290
Usually the motor sensor is not faulty if a stucked shutter caused this - that's why it make sense to remove it. If there's no SP to disable then you can't just bypass the sensor since the machine probably expect specific readings during shutter on/off routine.Comment

Re: mpc3500 sc290
Gift, IF, and only IF, the shutter is stuck then what you say about removing the shutter may be so, however, we are refering to the situation where sc290 is per description the 'closed' sensor not being activated or the motor faulty then what fix is possible ? If artificially tripping the 'closed' sensor, would that solve it ? , because with the laser unit out you can reach the sensors (but not to remove them I think).Comment

Re: mpc3500 sc290
Well, i did remove a shutter five days ago and there was no necessity to do anything else.!
Neither SP, nor bypass anything. It was an MP C3500.Comment

Re: mpc3500 sc290
Just pull the LD unit (easy), and remove ONLY the shutter plate (this is what binds). Leave the arms and springs attached.NEVER ASSUME ANYTHINGComment

Re: mpc3500 sc290
Oze,..I didn't say I wasn't going to bother or neither have I taken off the shutter, yet. Simply, before I spend two hours driving to other side of town to go the machine I want to be armed with more knowledge as to the remedy for all possibilities, including what if its NOT the shutter, and it is a sensor/ motor issue as listed in the sc codes in the manual !
Again, Mikadonovan, the shutter comes off easily yes, but WHAT IF ITS NOT the shutter, and its the sensor or motor ? What can i do then ??? Thats the million dollar question.Comment

Re: mpc3500 sc290
I think the gist of it is that quite a few of us now have said that "in our experience" the solution has been to remove the shutter plate.
As for driving for 2 hours to the call you don't have any other customers in that area to make it worth your while?
Not having a go but that's what most of us do..wait til the calls build up in that area then tidy up what we can....bugger driving 2 hours for one customer.
Definitely give the shutter plate removal a go...here in Australia we have a saying.."suck it and see" lolComment

Re: mpc3500 sc290
Had the same code on mpc 4500 two years ago, I removed the shutter , replaced the sensor
and motor all was in vain , at last the problem solved after IOB replacementLive for yourself and you will live in vain. Live for others, and you will live againComment

Re: mpc3500 sc290
In factory mode 2914-007 exists on MPC3500/4500. Maybe you could try it before disassembling the whole machineComment
