Re: Mission accomplished "license to thrill"
 
I'm looking for the information about the paperfeed for a long time and, thanks for the info.
For the timing between asf motor action and the paperfeed sensor, I'll try using adjustable 555 timer instead of mechanical. that way will be much easier for me.
Any better suggestion, please share.

sounds like a good idea... but keep in mind something has to move the platen into the pe switch at the correct time... its timing is crucial here.. you can trick it (asf sensor) with the 555 you would also have to do this with the pe! but theres no way to tell print end that way because every design and time to print is different! this is why epson uses this mechanical pe switch.. simple and reliable!

if you are keeping the pe it must be in sync (original distances etc) from the print head.. it has to tell the printer print has finished at the correct platen size or else you will get a paper feed error..

i tried over engineering this in the beginning of my quest aswell... I sought at a very reputable electronics firm to produce a micro controller-processor for the printer mod application. it came down to reliability, will it work sure! but for how long is the question? I had intentions of marketing these after we had a solution, but i couldnt get a guarantee on the life of them or the program.. I then went to the plc with a different company same results with combining the printer with third party electronics.. it ended up needing a separate power source for concerns of overloading the main board etc.. i was not confident with it just by the issues that arised in testing so i certainly wasnt going to put my name on this and market it, i like to sleep at night..lol:D i definitely lost some money with that experience, but i chalked it up at a learning expense.. simple is usually the best solution.. you can use a very small 2-3 inch belt to accomplish this right off the paper tray feed motor if you decide to go mechanical.. simple and reliable.. i try and change as little as possible as far as electronics, In fact none on my printer!!! the only thing i would ever consider is using a simple circuit with a contact and limit switches for a manual load, but i just cant justify doing this (i will demonstrate why here in the near future with the new printer design)epson has a pretty good printer and r&d.. i think ill trust em... lol:D

ussually...well as far as the posts i have read on the other side of these forums on various commercial printers... there non fuctioning or problems arise with the added firmware (outside of poor maintenace of the ink etc)... these elaborate electronic platen returns and such..well they all have to have some programming for this in the form of a plc or micro-controller... just look at any business that runs production machines or process based machines- they most if not all have an in house plc programmer! why? bugs etc programs dont last forever they have to be debugged..and bla bla bla.. hope you see my point here..

i think some of the best dtg,s to come will be a simple unit designed to function mechanically without additional firmware added to the original (for epson based printers)..most plc etc programming hasnt been tested long term or proven reliable on dtg,s.. this is a customer service nightmare especially when they spent 12,000 n up on one of these.. just look on the other side (TOP QUESTION WHEN PEOPLE ARE CONSIDERING BUYING ONE OF THESE COMMERCIAL MACHINES IS HOW IS THE COMPANYS CUSTOMER SERVICE) LOL... you hear all machines are similar but i would like the best customer service WHY? because they know they are going to break or malfunction at some point... that says we need a better machine.. theres one that has design features for disconnecting the printer it self for fast shipping to be fixed (it is my favorite commercial machine however)!!!!

i sure havent been knocking down epsons customer service door with any of my printers in the past because they work and well... we need this quaility reliability in a dtg.. and before it comes up sure dtg is a different animal with the inks especially white you have to do the maintenace!!!! but most things ive read are outside this realm as far as errors etc... its the added firmware.................... i dont know about anyone else but i dont care about the fact that its a modified epson based inkjet, there great printers-seems most want to distance themselves from this..not me.. i just like a reliable, well functioning machine..it can say epson on it every square inch for all i care as long as it makes me money...

sorry for the rant...cant help it sometimes..

This is the DTG printer I made that I want to make a platen out of plastic for. It should be lighter and give the printer a cleaner look.
My regular employer went out of business so I'm going to try to make this model and sell it. Any thoughts on how much I can sell it for? The shirt on the platen is one I printed on a C88 DTG printer I made. I am using this to give a comparison of the difference in the print size from the Epson C88 model and a DTG printer based on a Epson 2200. Should be the same for the R1900 model DTG. On mens large and xtra large t-shirts the print area looked to small on the C88 model. On the new model I can print up to 13" x 18" with the platen I have made, instead of 8.5" x 14". I have Multi Rip software and on a 13" x 18" print that is not a solid print, I plugged in the cost of the ink and it only costs .27 cents to print. I though this was pretty cheap. This model will also print on dark colored shirts too.

I use HDPE high density PE... and yes you can weld it...

however any thing you put heat to has a tendency to bow a bit... so after you weld it-> to pull the bow or slight warp out use a heat gun , heat it a bit and presto back to square... its welding temp is around 320 degrees..

i used 1/4 on the base and 3/16ths on the platen.. i also use aluminum L channel to stiffen the edges underneath the platen (counter sunk and pop riveted to the plastic)... this setup is very light;)

hope it helps..

Re: Mission accomplished "license to thrill"
 
Thanks for your comments, that really makes sense.
After I take some more observation of the printer movements, I give up the idea of 555 timer.
Need to do the real work before discuss further. Will use those details you post as guidance.
I is reaaly great have you on this forum.

Re: Mission accomplished "license to thrill"
 
Has anyone ever tried using an Epson R1800 with 4 x white for printing on black's.

I have heard that they have ink starvation problems. Its just that I have been trying for over a month to get an R1900 and I have a couple of R1800's laying about doing nothing.

Re: Mission accomplished "license to thrill"
 
The Epson R1800 has in starvation problems when used as a regular printer. It's worse on DTG conversion because it trys to put out even more ink. You can go with the 2200 they work well and can put out more ink than even the R1900.

Re: Mission accomplished "license to thrill"
 
Has the 2200 got the same print head as the R1900 ?

I think I read somewhere on her that German13 said that the 2200 was none too good for conversion but then that may have been somthing to do with it maybe not having roll mode before he started using sheet mode on his R1900.

sorry to hear about the employer, all to familar these days!!

as far as selling the dtg, thats going to be time+material+ profit margin!


kinda grey area..you have to see what kinda market there is for them and what a fair profit is after you manufacture it!!! its a risky venture due to the unknowns people want customer service! i guess if its priced right this could negate that factor..

i would go with the 1900 if you intend on doing this!! people will be more comfortable about getting parts!!! and its a much faster printer!:)

the 2200 prints nice, however its a discontinued epson printer... so parts are a factor..

the print head is not the same either..the 1900 has a coated head..etc its an eight channel either dual cmyk or cmyk-wwww for white ink printing..and it will lay down as much ink as you want.. its a fantastic dtg printer many commercial models are based off the 1900...

additionally it is a very fast printer..you can see this for yourself by watching spiders vid or an older t-jet, dtg kioske.. and compare that to an anajet sprint-mod 1-velocijet etc..its night and day print speed..

it all depends on what your trying to accomplish! but for the time effort and money you spend i myself would certainly use a new printer and current 1900 rip to match.. IMHO!

hope it helps..:)

Re: Mission accomplished "license to thrill"
 
Thanks Jeff, I think its sunk in now :) Getting a bit long in the tooth here !

Would love to get my hands on a R1900 but few and far between over here. A used one costs x2 more than you guys can buy a referb from Epson over there so looks like I will have to go for a 2200.

Whats the difference between 2100 and 2200 when it comes to a DIY DTG conversion.

Oh and speed is not really an issue here.

lol :D i just been the ginea pig..lol

i have tried alots of things with these printers..and most of my knowledge is from failure with testing.. but you have to fail before you succede;)

you are going to have to ask cmos or moffet on that one.. i did not spend alot of time with the 2200 because of the parts-print speed, so they are better versed on these printers then i, and have conversions they have done... just pm them;)

moffett8 August 27th, 2010 08:10 PM

Re: Mission accomplished "license to thrill"
 
Different print heads, 2200 can open up more to put out more ink but the R1900 has a Teflon coated print head. This is a plus and helps with clogs. Multirip supports both printers so either will work well as a DTG printer. The 2200 is not in production so there are no new ones available.
Also the 2200 drive the paper feed roller by gear and the R1900 is belt drive simular to the C88

The 2100/2200 are basically the same printer. 2100 was mostly sold out of the usa.

FYI - I was ordering parts for someone today and was told that Epson makes parts available for 7 years after they stop production of a printer.
