Cash Register Won't Print a Receipt: 7 Causes and an Action Plan for Cafés

If your cash register won't print a receipt, start with the message on the screen and find it in the table below. Almost always it is one of seven causes: the fiscal module is full, the connection is down, the order contains an item whose IKPU code can't be paid in cash, there is an IKPU or VAT rate error, a labelled product has expired, or a payment method in the POS isn't linked to the fiscal register. You can't sell without a fiscal receipt, even during an outage. So your cashier needs a 15-minute plan, and you as the owner need routine checks that keep the register from going down.

The golden rule: no selling "on paper" during an outage

Under Presidential Decree No. UP-5813 of 6 September 2019, a guest paying by card must get an online cash register receipt along with the terminal slip. A missing receipt, or one without a fiscal mark, counts as trading without a cash register. Handing out handwritten slips or jotting orders in a notebook to "ring them up later" is not allowed.

What to do: find the cause in the table, fix it or switch to an allowed payment method, and call your POS support line.

What not to do: reboot every device in sight or try to repair the register while the queue grows. Since 1 April 2026, some blocks are working exactly as designed. A greyed-out "Cash" button, for example, isn't a fault, and there's nothing to fix.

Table: symptom → cause → what to do in 15 minutes

What you see on the register	Likely cause	What to do in 15 minutes
The register won't open a shift and shows a module memory message	The fiscal module is full	Don't look for workarounds. Contact the technical service center (TsOTU) about replacing the module and tell the owner. If you have a second registered register, switch to it.
The receipt prints, but its status is "not sent" and the connection icon is red	No internet, so the register is working offline	Check the router and cable, and switch on the backup SIM card. Make sure the data reaches the operator within the required time.
The "Cash" button is grey and can't be tapped	The receipt contains an item whose IKPU code can't be paid in cash (alcohol, tobacco)	Offer the guest card or QR payment. Or split the order and put the restricted item on a separate cashless receipt.
"IKPU not found" or "invalid code" error	An outdated or wrong IKPU code in the item card	Check the code on tasnif.soliq.uz, fix the dish card and ring up the receipt again.
VAT rate mismatch error, often with corporate card payments	Wrong VAT settings in the register	Ring up the item with another card or payment method. Pass the settings issue to your accountant or support straight away.
A labelled product won't add to the receipt	A product with digital labelling has passed its expiry date	Take it off the shelf, offer a replacement and set the pack aside for write-off.
The POS shows the bill as closed, but there's no fiscal receipt	The payment method isn't mapped to the fiscal register, or the POS can't reach the module	Check the fiscal key connection (USB or module), resend the receipt for fiscalization and call support.

The 7 causes in detail

1. The fiscal module is full

A fiscal module is a physical device that protects receipt data with cryptography. Its capacity is measured in Z-reports, and every closed shift takes up space. Once the memory runs out, you can't use the online cash register or virtual register until the module is replaced. A full module is handed over to a TsOTU specialist. On buxgalter.uz there is a reader's question about a module that filled up and left the business unable to trade for a long time. That downtime is lost revenue, so check how full the module is in advance, not on the day it locks.

2. No connection to the operator

Without internet, the register can still issue receipts offline, but the data must reach the operator within a set period. Commercial sources quote different deadlines, so check the exact figure in the Regulation approved by Cabinet of Ministers Resolution No. 943 of 23 November 2019. According to nrm.uz, from 22 October 2026 it applies as amended by Resolution No. 393 of 20 July 2026, so always refer to the current version. Rules from other countries, such as Russia or Kazakhstan, don't automatically apply to Uzbek registers, so check them against Regulation No. 943.

3. The "Cash" button is disabled

The ban is based on Decree No. UP-246 of 10 December 2025. Since 1 April 2026, alcohol, tobacco and a number of other goods and services can't be paid for in cash. Subclause "d" of clause 2 was restated by Decree No. UP-175 of 27 August 2026, so check the list against the current version. On 3 April 2026, the Tax Committee published a list of 28,800 IKPU codes. If a receipt contains even one of these items, the whole receipt can only be paid cashless. On 27 March 2026, Deputy Chairman of the Tax Committee J. Abdiev explained that the "Cash" button stays disabled while a restricted item is on the receipt. Cashless payment remains available for the entire order.

A real-life example: a group at a chaikhana orders plov, tea and beer and wants to pay in cash. The cashier splits the bill: the beer goes on a separate receipt paid by card or QR, and the food and tea are paid in cash.

4. Wrong or missing IKPU code

Since 1 January 2022, receipts without an IKPU code are prohibited. IKPU errors, such as an outdated or incorrect code, are a common reason receipts fail. Check codes against the current classifier on tasnif.soliq.uz, especially after changing suppliers. If a receipt with an error has already been issued, correct it via "Receipt correction" in the "Online cash registers and virtual registers information" service on my3.soliq.uz.

5. VAT rate error

Since May 2025, new requirements apply to registering receipts paid with corporate cards. A register with incorrect settings won't issue these receipts and shows a VAT rate mismatch error. More generally, an online cash register can't be used if a receipt fails even one mandatory requirement in clauses 5 and 8 of the Technical Requirements. This is a settings issue, not a hardware one.

6. Expired labelled products

Since 1 March 2026, a receipt can't be printed for digitally labelled products past their expiry date (according to the nrm.uz legal database on the rules for online cash registers). In a café, this could be bottled water or tobacco. We covered what to scan at the register and what not to in "Product labelling in food service after UP-175".

7. A payment method isn't linked to the fiscal register

Sometimes an order is closed in the POS, but no fiscal receipt appears. One possible reason: a new payment method, such as a new QR provider or delivery aggregator, was added to the POS but not mapped to the fiscal module. That receipt never goes to fiscalization and has to be resent. It's also worth checking that the USB key or module is connected. Check the cable and connection, then call support.

Cashier cheat sheet: print it and stick it by the register

1. Read the whole message on the screen and take a photo of it with your phone.
2. Is the "Cash" button grey? That's not a fault. Offer card or QR payment, or split the bill.
3. IKPU or VAT error? Set that item aside, ring up the rest and tell the shift supervisor.
4. No connection? Check the router and cable, and switch on backup internet.
5. Register won't open a shift or mentions module memory? Call the manager right away, because the TsOTU needs to be involved.
6. Don't hand out paper slips instead of receipts or write orders down "for later".
7. Call POS support and give them the error text and the register number.
8. Note the time of the outage and the numbers of any orders that didn't go through, and pass them to the manager.

Owner checklist: what to check so the register doesn't go down

• Monthly: how full the fiscal module is. Order a replacement in advance, not on the day it locks.
• When you change suppliers or the menu: IKPU codes in dish and item cards against tasnif.soliq.uz.
• After 3 April 2026: which menu items are on the no-cash IKPU list (alcohol, tobacco). Show your waiters how to split the bill.
• VAT settings: your accountant checks the rate and the corporate card payment flow.
• Labelled products: weekly expiry checks on water and other labelled items on display.
• Payment methods: every new method (QR, terminal, aggregator) is mapped to the fiscal register. Run a test receipt before going live.
• Connectivity: backup internet from a second provider.
• Before and after 22 October 2026: the changes to Regulation No. 943 made by Resolution No. 393. Ask your accountant or register supplier to walk you through how they affect your register.

How AliPos handles this

The AliPos POS fiscalizes receipts in line with Uzbekistan's requirements and supports labelled products. A local server is installed on site, so when the internet drops, the register, waiters and kitchen keep working over the local network. Once the connection is back, data syncs with the cloud. EPOS fiscalization setup (USB key and SIM card) costs UZS 1,140,000 without a module and UZS 1,500,000 with a module. See the Fiscalization page for details. Support is available 24/7 at +998 55 704-99-99, and 99% of requests are resolved in under 15 minutes. That's about how long it takes before a lunchtime queue starts walking out.

FAQ

The register won't print a receipt. What should the cashier do first?

Read and photograph the error message, find it in the table above and follow the action in the right-hand column. Selling without a receipt is never allowed.

Kassa chek chiqarmayapti — nima qilish kerak?

The steps are the same: identify the cause from the on-screen message (module, connection, IKPU, VAT, labelling or payment method), never hand out paper slips instead of receipts, and call your register support.

Where do I hand in a full fiscal module?

A full module is handed over to a TsOTU specialist. You can't use the online cash register or virtual register until it's replaced, so keep an eye on capacity in advance.

Why can't I tap the "Cash" button?

The receipt contains an item whose IKPU code is on the list of goods that can't be paid in cash since 1 April 2026 (UP-246). Move that item to a separate cashless receipt, or have the whole order paid by card or QR.

Can I hand out paper slips while the register is down?

No. Under UP-5813, a receipt without a fiscal mark counts as trading without a cash register. Use a backup registered register or fix the cause of the outage.

How do I fix a receipt that was already issued with an IKPU error?

Use "Receipt correction" in the "Online cash registers and virtual registers information" service on my3.soliq.uz. Fix the code in the item card in your register too, or the error will happen again.

If your register stops more often than you'd like, start with the checklist above and work through each error. And if you're considering a register with a local server, fiscalization and 24/7 support, take a look at AliPos pricing or leave a request at alipos.uz/en/connect. We'll call you back and show you how it would work in your venue.
