Billettskanneren virker nå.

Because billettskanneren is the definite singular form: the ticket scanner.

• en billettskanner = a ticket scanner
• billettskanneren = the ticket scanner

In Norwegian, definiteness is often shown by adding an ending to the noun:

• -en for many masculine nouns
• -a or -en for many feminine nouns
• -et for neuter nouns

Here, billettskanner is usually treated as a masculine noun, so the definite form is billettskanneren.

Yes. Norwegian commonly combines nouns into a single compound word.

• billett = ticket
• skanner = scanner
• billettskanner = ticket scanner

This is very normal in Norwegian. English often writes these as two words, but Norwegian usually writes them as one.

Here, virker means something like works, is working, or functions.

The infinitive is å virke.

In this sentence, it means the scanner is functioning properly now. Depending on context, å virke can also mean other things, such as:

• to seem / appear
  
  • Det virker bra = It seems good
• to have an effect / act
  
  • Medisinen virker = The medicine works

So virker is a flexible verb, and context tells you which meaning is intended.

Yes. Fungerer is also very natural here.

• Billettskanneren virker nå
• Billettskanneren fungerer nå

Both can mean The ticket scanner is working now.

A small nuance:

• virker is very common and broad
• fungerer can sound a little more specifically like functions properly

In everyday use, either one is fine in a sentence like this.

Because that is a very common place for adverbs of time in a simple main clause.

• Billettskanneren virker nå = The ticket scanner works/is working now

Putting nå at the end sounds natural and neutral.

You can also move it for emphasis:

• Nå virker billettskanneren = Now the ticket scanner works
• Billettskanneren virker nå = more neutral, with now at the end

Both are grammatical, but the focus changes slightly.

It is present tense.

The forms are:

• infinitive: å virke
• present: virker
• past: virket
• past participle: virket

So Billettskanneren virker nå is in the present tense, even though in English you might translate it as either:

• The ticket scanner works now
• The ticket scanner is working now

Norwegian often uses the simple present where English might prefer the present progressive.

Because Norwegian usually marks definiteness directly on the noun instead of using a separate word like English the.

So:

• scanner → skanner
• the scanner → skanneren

And with the compound:

• ticket scanner → billettskanner
• the ticket scanner → billettskanneren

A separate determiner can appear in some structures, especially with adjectives:

• den nye billettskanneren = the new ticket scanner

But in your sentence, no separate word is needed.

The basic order is:

Subject + verb + adverb

• Billettskanneren = subject
• virker = verb
• nå = adverb of time

So:

Billettskanneren virker nå.

This is standard main-clause word order in Norwegian.

Because Norwegian is a V2 language in main clauses. That means the finite verb usually comes in the second position.

So if you start with Nå, the verb must still stay second:

• Nå virker billettskanneren

Breakdown:

• first position: Nå
• second position: virker
• then: billettskanneren

You do not normally say:

• Nå billettskanneren virker in a normal main clause

That sounds wrong because the verb is no longer in second position.

A rough guide might be:

BIL-let-skan-ne-ren VIR-ker nå

A few notes:

• billett has a clear tt
• sk before a is usually pronounced like normal sk
• virker has a short first vowel
• nå has an å sound, roughly like the vowel in British law or more, though not exactly

If you are learning Bokmål pronunciation, remember that pronunciation can vary by dialect, even when the written sentence stays the same.

It is a borrowed word, ultimately from English scanner, but it is fully used in modern Norwegian.

Norwegian often adapts borrowed words to Norwegian spelling and grammar:

• en skanner
• skanneren
• skannere
• skannerne

So even though the word is borrowed, it behaves like a normal Norwegian noun.

Yes, it sounds completely natural.

It is short, clear, and idiomatic. A native speaker might say it in situations like:

• after fixing a machine
• after a restart
• when telling passengers or staff that the device is working again

It has a very normal everyday style.
