Register locked up during report printing and just beeps

There are special codes on most machines depending upon the type of report you need. Use the codes in the manual to create a report. If you don't have a manual, one of the users has most here:

try to do an 'initial clear'
turn power switch on right side of reg to OFF pos
turn control lock to P position
press and hold SBTL key and turn power switch to ON pos
should print 'Initial clear ok'
might need to repeat a couple of times

What model is you till. Please specify

how many times beeps ? is it short or long ?
did you check ram module ?

Normally a faulty mode lock

Dell beep codes:

If your computer beeps during start-up:
Run Dell Diagnostics to identify a more serious cause.

Beep Codes Your computer might emit a series of beeps during start-up if the monitor cannot display errors or problems. This series of beeps, called a beep code, identifies a problem. One possible beep code (code 1-3-1) consists of one beep, a burst of three beeps, and then one beep. This beep code tells you that the computer encountered a memory problem.
If your computer beeps during start-up:
Dell Diagnostics to identify a more serious cause.

Contact Dell for technical assistance.

These don't beep for no reason. There must be something wrong, maybe your fly is open. I would find out the location of the beeper. It will have two wires, cut one and your beeping will stop.

"Z" (Prints End-of-Day Management Reports and Resets Totals) - Prints the "Z" management report at the end-of-the-day and resets totals to zero (except "locked-in" grand total).
To print Management Reports, slide the control switch to the "X" or "Z" position as needed, then press the [amt tend/TOTAL] key. Refer to explanation starting on page 37.
"X" AND "Z" SALES MANAGEMENT REPORTS
__________________________________________________________________
Transaction data is maintained in the memory of the cash register as long as the battery back-up system is in effect. This data can be printed as a report for management review.
The Management Report can be printed from either the "X" or the "Z" position on the Control Switch.
"X" POSITION REPORT (Refers to a mid-day reading)
The "X" position report prints the accumulated information and RETAINS ALL TOTALS IN MEMORY. Use this position to print periodic readings of transaction information at any time through-out the day. (Some users call the X-report a mid-day report).
"Z" POSITION REPORT (Refers to an end-of-day or close-out reading)
The "Z" position report prints the same information as the "X" report. However, once this report is printed, ALL TRANSACTION TOTALS ARE RESET TO ZERO except the Grand Total. (Some users call the Z-report an end-of-day report).
NOTE: To prevent accidental printing of the "Z" report, set the security code as explained in the SECURITY CODE section.
Once this code is set, a "Z" report will not print until the security code is entered. If a "Z" report is attempted without entering the security code, the prompt "SEC Code" will appear in the display.


PRINTING THE SALES REPORT
IMPORTANT: Once a "Z" reading is taken, it cannot be duplicated, so be sure to have plenty of paper in the register.
1. Set the Control Switch to either the "X" or "Z" position.
2. Press the [amt tend/TOTAL] key.
NOTE: If a security code has been assigned, be sure to enter the security code before pressing the [amt tend/TOTAL]
key.
TO CLEAR THE GRAND TOTAL:
1. Set the Control Switch to the "prg" (Program Mode) position.
2. Type [2], type [0], then press [RA].
After this operation, the grand total resets to zero.
