This model the SER-7000 uses 2.25" thermal paper rolls and does not require an inking device. The 2.25" thermal paper it uses is one of the most common paper sized on the market today because it is the same as most credit card machines use. We reccomend ussing the larger roll that fit in the credit card machines because of those don't contain much paper. Of course also because it uses thermal paper is why there is no ink device required. If you have the optional kitchen printer attached that would require different paper and possibly ink ribbons too.
While this is an older model we still offer support for the SER-7000. We can assist with programming, reporting and troubleshooting issues with this register. We also stock the keyboard cover, cash drawer insert and certain other parts.
