Hi folks,
I am having a problem with slight lines across solid images on the Cadet.
Anyone else had this problem?
I have tried different quality materials and printed it on normal and fine but it is still showing.
Any hep greatly appreciated

Ian,
I assume your "cadet" is a printing machine! in which case i would say the print heads need cleaning.
if it's an old one it might need new heads, they don't seem to last long if you are using it a lot.
long john.

I had this problem. Cleaning and soaking the heads improved matters for a while then the problem returned. B & P's engineering department eventually discovered that my Cadet has the correct heads fitted but with a wrong/different manifold. Replacing the heads with the correct type eliminated the problem completely.

I hope this helps.

Run a print test, check all the numbers on the small lines for each colour it will print, input these into the cadet (should be in your manual. Also try feed, this can cause lines if you have feed set to pull a 50mtr roll for talks sake. When the vinyl gets near the end off a roll the weight has changed that it has to pull through machine.

Hope this make sense, as these are the first things I check if I get lines on the Grenadier.

Oh and obviously print clean, may have to be a "heavy" clean which uses alot of ink :evil: :(

banding

guys, guys,guys,

before you advise about head cleaning and soaking,
there are a question to ask.

are you using the correct profiles for the media?

the cadet comes with some profiles but not many,

i've noticed that if you save money on some machines you lack some support of the profile kind,

remember the cadet is a bastadised machine,

but i know it should run ok, and im sure it will given the correct settings

We use the same materials and the proper profiles for said materials and the odd occasion we get the odd band now and again. There are many ways this can be caused but the ones I pointed out are the more common culprets.

hi outline, please be specific on fault or i will have to delete your posts mate... :-?
if you think the machine is bad and want to say so, fine, but please shed some light on why? many look for other peoples veiws to make their own mind up on purchasing a machine. simply saying something is bad and giving no real reasons is not allowed. sorry :roll:

No problem,

Poor extremely grainy pantone / solid colours to the point that most are unsaleable in production mode.
Evident banding present in most colours.
Small work is almost impossible as it floods.
Small vector print and fill work? forget it!
Best in quality mode, but quality mode will flood inks on smaller jobs
Production is too grainy and low quality.

I've not been able to sell one job / output this machine produces.

Machine set up 3 times by dealer, correct profiles, correct media, correct inks, correct RIP, correct operator, poor machine.
£13000 out of pocket, could have bought myself a nice Ducati

Heater ain't bad though, warms the office up, of course when it doesn't throw up the old 'heater voltage error' on the display and then nothing works, it is slightly better after the new printheads after just 1 month.
Will I ever see a profit on my cash (not finance) outlay, as I see the future, not a chance.
Anyone got an edge for sale?

Maybe not :wink:

just one problem then? :wink: :lol1:



its too late for me to try help, but im sure others maybe able to and hopefully b&p will reply to this post. :D



my own opinion, if you have a machine with so many faults, you have a faulty machine. simple as that...
im using the same machine but wider and never had any problems what so ever... :roll:

Outline, I'd agree and say you have a lemon mate. How long have you had it? I'd seriously pressure your dealer to replace it, certainly here we have laws that will assist you in that. May be worth a talk to a solicitor first.

Also, I'd get a second opinion from another cadet owner. See if they will come over and run the machine with files they know to be good. They may have enough experience to see what may be going wrong if they have had a machine for a while.

I had lines in the prrint of my Roland, and had the warranty people out to check it out. They had no idea why it was doing it because it was intermittant at the time.

Finally had a 'heart to heart' with my supplier and he sent out his rep who had is own shop before he became an employee.

He picked the black head was faulty, changed it and it has never printed so good. It must have been faulty from the start, but I knew no better.

My supplier even covered the costs himself because Roland would not pay as they did not diagnose it. Luckily I am a big customer and he was happy to support me, but the point is, if I had not found someone with practical experience I would have been an irate or very disappointed customer by now.

The first thing I would do tho is a 'heavy' clean. Costs a bit, but that is the first this a repair guy will do anyway. Vectorwise has given you good advice here, I'd follow his suggestions before going any further.

Hope it works out,

Cheers
Shane

On the Roland these are all evidence that the heater is not heating the print media enough. I know one guy with had a faulty thermostat, and had similar problems. Once it was replaced, going fine.

Best in quality mode, but quality mode will flood inks on smaller jobs
Production is too grainy and low quality. This could be heat related too on the Roland. If you have errors relating to the heater, has this been checked?

Sorry mate, just trying to think this thru.

Cheers again

I don't know where you are, but I would be very happy to show you my Cadet producing stunning print quality on vinyl and on banner.

I've certainly had teething problems with the machine and had to nag, but B & P got it working and its now running fine.

From what you've said you may have hardware faults but before assuming this you need to evaluate your RIP/Material/Profile match. If any of these are wrong your prints may not be as good as they could be or they may be rubbish. One wrong parameter can make a good printer look terrible.
