No. 次第 has more than one use in Japanese.

In this sentence, 確認し次第 is the grammar pattern verb stem + 次第, which means:

• as soon as ...
• once ...
• immediately after ...

So 確認し次第 means as soon as we confirm.

This is different from the other 次第 meaning depending on or according to the circumstances.

Because this pattern attaches to the masu-stem of the verb.

• 確認する → stem: 確認し
• 確認し + 次第 → 確認し次第

So the structure is:

• V-stem + 次第

Examples:

• 分かり次第 = as soon as I know
• 準備でき次第 = as soon as it is ready
• 確認し次第 = as soon as we confirm

So 確認する次第 and 確認した次第 are not the correct forms for this grammar pattern.

Both can mean once / after confirming, but 確認し次第 is more formal and businesslike.

確認し次第

• formal
• often used in emails, notices, office language
• strongly suggests as soon as that happens, the next action will follow

確認したら

• more everyday and conversational
• can simply mean if/when I confirm

So in a customer-service or workplace sentence like this one, 確認し次第 sounds much more natural than 確認したら.

Because 形名と製造番号 is treated as one combined object.

The structure is:

• [形名と製造番号] を 確認し
• [修理依頼] を 出します

So the first を marks the whole phrase 形名と製造番号 as the object of 確認する.

This is just like saying:

• A and B を確認する = confirm A and B

You do not need:

• 形名を製造番号を確認し

That would be incorrect here.

Here, と simply means and and connects two nouns:

• 形名 = model name / model number / product designation
• 製造番号 = serial number / manufacturing number

So:

• 形名と製造番号 = the model number and serial number

This と is a straightforward noun-connector. It lists both items clearly.

形名（けいめい） usually refers to a product's model designation. In practice, it is often very close to model number.

It is similar to 型番, but the nuance can vary by company or industry:

• 形名: formal product designation, often seen in manuals, support documents, or manufacturer language
• 型番: very common everyday word for model number

So for a learner, treating 形名 as model number / model name is usually fine.

修理依頼を出します means submit a repair request.

The verb 出す here does not mean physically take out. In office/business Japanese, 出す is often used for things like:

• submitting a request
• filing a report
• sending in an application

So:

• 修理依頼を出します = we will submit/file a repair request
• 修理を依頼します = we will request a repair

Both are possible, but the nuance is slightly different.

修理依頼を出します

• sounds procedural / administrative
• focuses on officially submitting the request

修理を依頼します

• sounds more direct
• focuses on asking for the repair itself

The sentence you were given sounds like workplace or customer-support language, so 修理依頼を出します fits very well.

The subject is omitted, which is very common in Japanese.

From context, the implied subject is probably:

• we
• I
• our company / our staff

So the sentence naturally means something like:

• Once we confirm the model number and serial number, we will submit a repair request.

Japanese often leaves out subjects when they are obvious from the situation.

Because Japanese non-past form covers both:

• present/habitual actions
• future actions

So 出します here means will submit.

This is normal Japanese usage. Future meaning is often shown by context rather than by a special future tense.

In this sentence, the sequence is clear:

1. confirm the model and serial number
2. then submit the repair request

So 出します is naturally understood as future.

It is polite and fairly formal, especially because of:

• 確認し次第
• 出します

This sounds like something you might see in:

• a business email
• customer support communication
• office correspondence
• a service update

It is not extremely stiff, but it is definitely more formal than casual conversation.

The comma separates the as-soon-as clause from the main action:

• 形名と製造番号を確認し次第、
• 修理依頼を出します。

So it helps the reader see:

• first, the condition or trigger
• then, the main result/action

It is mainly for readability. You may sometimes see similar sentences without a comma, but the comma is very natural in formal writing.
