Default Printing wider than original printer can

Guys:
I'm gonna make my DTG probably from Epson r1900, but i need a wide print area, not just the 13' that the r1900 gives. I know i can make the needed mechanical changes, stretching whatever i need to stretch, and replacing what i need to replace, but i'm not sure if the printing head will move beyond its manufacturer limits. I have been told by epson technician that it is limited from the printer mainboard. If it is the case, is it possible to replace the firmware with a hacked one, in such way that the printer believes, for example, that Letter paper is 20'x40'? I'm a software developer, i believe i could make the changes but i'm just starting and i need a lot of information. I guess there is a table somewhere with the paper sizes that might be changed.
Any information will be very appreciated.
Thanks,
Martin.

You would probably need to find a longer timing CR scale also so the head would know where it is. Maybe one out of a 3800 and up printer.

Absolutely, i'm gonna need that and several more spare part items. I can buy some of them in epson. I have some others at home, i will modify some of them, and even make some others from scratch. But, i know it is something i can achieve. There are some other things that i still need to figure out, like the one i'm asking in this thread. Hope anybody knows!

Seems like it would be easier to just start with a larger printer than try to piece one together and get the firmware to match up. Otherwise, you would see the dtg manufacturers doing the same thing to same money. WOuld be interested to know how it turns out.

I thought of this too and caused me a major headache. Its like building a printer from scratch.
I hope i had a 1900 so i could be more helpful.

Default Re: Printing wider than original printer can

Mark: Well, i have some reasons:
1- There is not a lot of very wide printers in Argentina. Even Epson does not have directly but through some distributors. That makes them expensive, and therefore difficult to afford.
2- I believe that buying wide assemblies to epson would be a good choice if i wanted to make machines for sale, and had a lot of money to make investments, because it is more practical, and those parts work very well already. But i'm planning to make one to do some printing work and start a small company with low capital.
3- This is just research, so i can still change my mind if this approach is not tecnically possible to me, or if i find a low cost very wide printer (this would save me time and trouble, i absolutely agree with you in this point).

I understand your reasoning, but think you are going to have too many challenges trying to frankenstein two printers together. Just my opinion. Best wishes,

Mark

Default Re: Printing wider than original printer can

Lets figure that you made a new firmware, how will you test it?
I suggest that ,if you are serious about this, to build the new wider printer.
You will need at least a new 20" shaft for the carriage and a new encoder strip with the same vertical lines per inch. The worst scenario is that you will get a fatal error when you power up the new printer. This is the first obstacle to overpass, the start up checks.

Cmos: It seems you have interesting info about this topic.
I do not have much experience writting firmware, but working as software developer for years, in some specific situations, i had to hack certain low level things. Sometimes i did it for fun, like memory cards, to get more ammo in games, and sometimes in work, for example to steal some vectorial information from rare file formats. I believe that the movement limits are just a number somewhere in the firmware, perhaps in a table with standard page sizes, and dimentions (vertical lines numbers for each). This research points to try to determine if i'm right, and get as much info as possible about this. I will not do anything unless i'm 90% sure. I know it is risky, i might brick the printer. In the worst scenario i would buy a new mainboard, fix the printer and stop trying. But if i get good results, many people will be happy to know, including me!!
Please let me know what you think. I'm serious about this research.

Default Re: Printing wider than original printer can

I feel i'm not being clear enough:
i would like to read or download a firmware file of an updateable printer model if possible, edit it with hex editor to change for example the number of vertical lines for some specific paper size, and finally update the printer with that file. I would take one or two edited bytes. It is a hacking work that consists on making suppositions of how the critical info is organized in that file, find some distribution or patterns that support the theories and apply the modifications.
It sounds simple, doesn't it?
Maybe i'm wrong, but i did this many times with other stuff, i believe this one could be similar.

I know what youre talking about. what you have in your hands? You have a 1900?
If you dont, i think a 2100/2200 is a better choice for you. Its cheap, you can find a lot of stuff because it is more than 6-7 years on the market. I found the service manual and the adjustment program very easy.

Default Re: Printing wider than original printer can

Thanks for the info. I did not buy it yet. I'm searching notes about firmware upgrading in epson printers. The desired scenario would be an updateable printer, wich's firmware is not encoded, with enough channels for white color (i was told that 7 or 8 are needed), and easy to find in Argentina. When i find one, then i'll make the studies over the firmware file, buy the printer, hack the firmware, upgrade, complete the project, and share it with pics and videos.
