Question about Casio DR-210HT Scientific Calculator

1 Answer

Jammed gears Went to change ribbon and now gears will not turn - when I try to feed get "E" error. Will clear but feed gives "E" again. Opened another unit to compare and some thing happened. Now 2 units not working. There must be a gear release somewhere but I can't find it. Reset on bottom does nothing. Put top back on and still nothing. Thanks

Re: Jammed gears

Alignment of the gears is needed to solve this case. Although only authorized technician can only align these gears because it is too complicated.

Print is very light even after replacing ribbon.

My first thought is that the numbers being "hammered" against the paper are not reaching far enough. Test this theory by putting two layers of paper into the paper feed, (Fold the end of the roll over onto itself) and try printing again. It could be designed for a thicker paper.
Alternatively the new ribbon may also have dried out. Rub the ink ribbon with a paper, or pencil eraser and see if the ink readily comes off, perhaps use a pencil eraser to press it against the paper being fed through the machine.

These are diagnostics to find the error. Further investigation might be to see if there is any particles in the machine preventing it from hammering the numbers against the paper. Something might be in the way of the moving parts, something about the size of a paper hole punch paper, or pencil shaving. Shaking it vigorously upside down might solve this problem.

Good luck ;)

Feed button will not work is there anything I can do

Did you try holding the feed button down for a few seconds? If that didn't work check your batteries maybe they went dead.

Paper will not feed through printer part

cut the paper evenly with scissors before attempting to feed it into the paper entry port. If you just rip it, it will jam or fail to feed.

I was using a program that I entered into the program area of my TI-84. It worked perfectly and then I went to use it again, now I get this error message that says :ERR:DATA TYPE. What does this mean?

If it worked perfectly before then it should continue doing so. However when you used it the second time something might have changed in the variable you are feeding it. Foe example if the program needs a parameter A that is supposed to be integer (whole number) but now A stores a decimal value then A is of the wrong data type and the program complains.
I think you should clear all variables and all lists and restart the program. It may be safer to archive the program, then reset the RAM of the calculator. After that, unarchive it and run it.

Gives error memory message when tries to change

See if the cursor is checkered. If so, the calculator is out of memory.
You may have very little memory available and then wanted to create a table with a very small DeltaTbl (the table step). If the step is small, and the domain is large, very many points will have to be generated and that may make the calculator unable to comply for lack of RAM.

I suggest you free some Ram by clearing the lists, clearing the entries. To do so you press [2nd][MEM][3:Clear Entries] to clear entries, then press [2nd][MEM][4:ClrAllLists] to clear the lists.

Alternatively, you can just reset the Ram by pressing [2nd][MEM][7:Reset][1:All Ram][2:Reset][ENTER]. Then clear the Ram Cleared message and start again your table.

Hope it helps.
Thank you for using FixYa and for rating this solution.

Inserting paper- I'm not sure exactly where the leading edge of the roll goes - it doesn't seem to feed when I press the feed button, although the wheels and gears do turn.

Try to load the paper again --- there is a slot just infront of the printer
Make sure u turn the switch to "PRINT" position

How do I change the ribbon on my casio hr-8tm calculator?

Place the roll on the wire thing at the back (I don't think it matters which way round); push the paper through the slot at the bottom of the back and then (having taken the clear plastic cover off) push it along the bottom inside at the back as far as you can then start to press the feed button; keep feeding it with your finger and pushing the feed button asnd it should pick up eventually.
