There are three measurements required when dealing with Thermal Till Rolls. These are the Width, Diameter and Core Size. these are explained in the below subsections, if you require further help please contact us for assistance.
When measuring Thermal Till Rolls, the dimension reffered to as the “Width” is the most important measurement.
You can either take this measurement directly from the roll or from a receipt that has already been printed out.
If taking this measurement from the roll please refer to the below diagram which will show you where to measure.
If you are taking the measurement directly from a printed receipt you measure the slip of paper from left to right in the direction of the text printed on it. you must measure from edge to edge straight accross. Remember to be as accurate as possible in mm as small discrepancies in size can be vital when purchasing till rolls!
The regular paper width is 37mm,44mm,57mm,80mm or customized
The diameter of till rolls can vary from anything as small as 24mm to over 200mm. The bigger your diameter, the more paper that is on the roll. when measuring the diameter of your roll, it is important to never purchase a roll with a diameter bigger than the recommended size by us. This is as the roll may not fit in the machine. However you may always by a smaller roll, it may be cheaper but be aware it will not last as long.
To measure the diameter, you must measure from edge to edge of the till roll going directly through the centre hole in the roll (The Core) the best way to do this is to put the roll down on a flat surface, with the flat side of the roll on the table so that it cannot roll. this way you can be sure you are measuring the correct side of the roll.
More recently Core size has become less-relevent when purchasing thermal till rolls. The core is used in some cases where a plastic or sometimes metal tube (a spindle) feeds through the hole in the roll (the core) to hold it in place and assist in the feeding of paper through the printer. there are three main / more popular core sizes in the market place currently. – 12.7mm, 17.5mm & 25.4mm.
If the roll just sits in the machine (or sits in a “well”) then the core size does not matter, however the smaller the core is on the roll you are purchasing the more paper there will be in its place.In other words,you should care about the paper diameter as well as paper length when purchasing paper roll however if your machine does have a spindle that has to be used, then your core size must be matched to avoid purchasing a roll which will not work.
Description of Paper Roll:
In general,we usually describe paper roll as : Width x Diameter x Core.Let’s say 80x80x12mm paper roll,it means the width is 80mm,the diameter is 80mm,while the core is 12mm. Another sample is thermal receipt roll 57x40x12mm,that means the width is 57mm,the diameter is 40mm,while the core is 12mm.
Generally speaking,Any paper roll size is acceptable for us.If you are not sure what’s the paper size you need,Contact us,we would love be more than happy to help you.
